Interactions with the AutoCAD Ribbon crashes AutoCAD on Windows 10

It seems that a recent Windows Update for Windows 10 has caused issues with AutoCAD versions…

  • AutoCAD 2012
  • AutoCAD 2013
  • AutoCAD 2014

…whereby any interactions with AutoCAD’s Ribbon, Status bar, or Right clicking the Command line causes AutoCAD to crash out instantly with:

Error: Unhandled Exception

We believe this issue is caused by the new .NET 4.7 update which came down as part of KB3186568

If you have this update and are experiencing issues as described above, you should uninstall KB3186568:

  1. Right Click the Windows Start Menu in the bottom right and pick “Programs and Features

    Select Programs and Features by Right-clicking the Windows 10 Start Menu

    Select Programs and Features by Right-clicking the Windows 10 Start Menu

  2. Click on “View Installed Updates” in the top left…

    Go to View installed Updates

    Go to View installed Updates

  3. Right click the entry for KB3186568 and click “Uninstall
    Uninstall KB3186568

    Uninstall KB3186568

    1. please reboot as requested
  4. Once rebooted, now try your AutoCAD – it should be working fine now.

If you do not see KB3186568 in your Installed Windows Updates listing, most likely you are running on the Windows 10 Creators Update (version 1703) which comes pre-installed with .NET 4.7, and cannot be uninstalled. In this case, most likely, you will need to obtain an older version of Windows 10, preferably the Windows 10 Anniversary Update (version 1607) or earlier. A list of Windows 10 versions can be found here https://en.wikipedia.org/wiki/Windows_10_version_history

To find your version of Windows 10

  1. Right Click the Windows Start Menu in the bottom right and pick “Run
  2. Type “Winver” then Enter

It seems that Windows 7 and Windows 8 seem to me a more reliable platform for these versions of AutoCAD…

Opening AutoCAD DWG file gives “Drawing File was created by an incompatible version” message

If you are trying to open a DWG file with AutoCAD and you get the message “Drawing File was created by an incompatible version” it’s because somewhere along the line your AutoCAD DWG files were saved with a newer version of AutoCAD.

All is not lost, you can make them open again in your version of AutoCAD, you just need to download the free DWGTrueView App from Autodesk – http://www.autodesk.com/products/dwg/viewers

Once installed, start DWGTrueview and open the DWG file in question, then save as making sure to select the lowest DWG file version that matches your version of AutoCAD.

Installing Autodesk Land Desktop 2005 on Windows 7, Windows 8 and Windows 10

Installing AutoCAD LDT 2005 on Windows 7, Windows 8, Windows 8.1 and Windows 10 32bit or 64bit can be very easily defined in these short steps…

NOTE: These steps do not bypass normal Autodesk licensing/authorization, you should expect to use your own serial numbers in the normal way.

  1. Obtain your copy of the Longbow Converter here
  2. Copy your LDT 2005 installation CD media to your hard drive, to a folder path c:\Autodesk\ldt2005 
    1. NOTE: If you have more CD’s, simply copy the contents of each CD directly over the top of Disk 1, basically, overwrite all files in your previously copied c:\Autodesk\ldt2005 folder with the files from each of the CDs
  3. Next, start the Longbow Converter tool
    1. select the 2nd tab named “Old AutoCAD Installer Reviver
    2. pick the c:\Autodesk\ldt2005 folder (where you copied your LDT CDs to on your hard drive)
    3. click the Run Old Installer button.
      1. Read and understand all the prompts before pressing OK.
      2. Once the setup starts, stop and read the next step…
  4. In the setup program, navigate through each setup dialog as normal, with these exceptions… (if you cannot move past the first screen in the setup, see Trouble Shooting below)…
    1. When you click the Install link from your setup you may see a dialog box appear saying – “This program has compatibility issues” – simply check the “Don’t show this message again” and then click the “Run the program without getting help”.
    2. When you arrive at the installation folder path setup dialog, **it’s vitally important to make sure you install to c:\ldt2005 (not C:\Program Files (x86)\Autodesk Land Desktop 2005 that is defaulted)**.
    3. If asked to reboot after the install, say NO
  5. Once installed
    1. do not reboot
    2. make sure you fully close the AutoCAD setup program (because the Converter is waiting for the setup program to fully close) then
    3. go back to the Converter tool
    4. select the 3rd tab named “Old AutoCAD Program Reviver
    5. pick the newly installed c:\ldt2005 folder
    6. click the Fix Old Program button.
  6. Now you can run your Autodesk LDT 2005 on Windows 7, Windows 8 and Windows 10, both 32bit and 64bit.
    1. NOTE: When starting AutoCAD, if you see a warning dialog when you run saying “This program has known compatibility issues“, simply click “Don’t show this message again” and then click “Run the Program…

Troubleshooting:

– If you are seeing this error when running either the “Import LandXML” or “Export LandXML” commands

LandXML Export - Run-time error '429' ActiveX component can't create object

LandXML Export – Run-time error ‘429’ ActiveX component can’t create object

then LDT 2005 Fixed VBA Modules into the same folder as your acad.exe (using the instructions above, it should be c:\ldt2005)

– If you are unable to activate your product, or the activation  setprocess crashes immediately on startup:

Install 32bit AutoCAD 2016 on Windows 7, Windows 8 and Windows 10

NOTE: This blog post specifically solves issues related to these error messages on installation of 32bit AutoCAD 2016 on 64bit Windows…

  • “This operating system is not supported by AutoCAD®”
  • “You cannot install this product on the current operating system”
  • “You are attempting to use a 32-bit installer on a 64-bit operating system”
  • “This is a 32-bit AutoCAD® 2016. It cannot be installed on 64-bit Windows”

Installing 32bit AutoCAD 2016 on Windows 7, Windows 8, Windows 8.1 or Windows 10 64bit can be very easily defined in these short steps…

NOTE: These steps do not bypass normal Autodesk licensing/authorization, you should expect to use your own serial numbers in the normal way.

  1. Obtain your copy of the Longbow Converter here
  2. If you have CDs (if not check (3) below):
    1. Using Windows Explorer, backup/copy Disk 1 of your AutoCAD 2016 install media to your hard drive, to a folder path c:\Autodesk\AutoCAD2016
    2. If you have more CD’s, backup/copy them all directly over the top of Disk 1, overwrite all files in your previously copied c:\Autodesk\AutoCAD2016 folder
  3. If you have a single self extracting exe downloaded from Autodesk called something like AutoCAD_2016_English_Win_32_64bit_en-us_Setup.exe
    1. Simply run the exe, it will ask to unzip to a folder inside of c:\Autodesk, make a note of the folder for later use (we’ll refer to it from here as c:\Autodesk\AutoCAD2016), now click OK. Wait until all of the files have extracted, when they do, the AutoCAD 2016 setup will automatically launch – simply close it and move to the next step.
  4. Now, start the Longbow Converter tool, select the 1st tab, pick the c:\Autodesk\AutoCAD2016 folder, and click the Convert button.
  5. Once the conversion process is complete, click Install/Run Setup to start setup. Simply install as normal.
    1. Once installed, we recommend you disable the AutoCAD Communication Center/InfoCenter toolbar as it uses a lot of memory, causes slow startup and most people don’t use it anyway!
  6. Now you can happily run your AutoCAD 2016 32bit on Windows 7, Windows 8, Windows 8.1 and Windows 10!

Troubleshooting:

– If your AutoCAD starts with a blank white screen…

  • Try turning down your screen resolution, if this doesn’t help…
    • from the Converter tool, pick the Tools->Clean Compatibility settings

– If you are unable to activate your product, or the activation process crashes:

AutoCAD “There was a problem sending the command to the program”

If you are seeing the message “There was a problem sending the command to the program” when you double click a DWG file from Windows Explorer, then the solution is to follow the instructions listed for your AutoCAD version below:

If you do not see your version of AutoCAD listed, or you are not an AutoCAD user, leave me a comment below and I’ll check it out for you.

AutoCAD running slowly on Windows 10, Windows 7 and Windows 8

If your are running on Windows 10, Windows 7, Windows 8 or Windows 8.1 and your AutoCAD has suddenly started running slowly, or perhaps you are seeing “AutoCAD is not responding” message more than usual, then read on…

Check your installed programs… See if you have “Microsoft WSE 3.0 Runtime” installed, if so, simply uninstall it – it’s been replaced in Windows 7 and Windows 8 with WCF, which is built in.

AutoCAD File->Save or File->Open Crash…

If are experiencing crashing problems using the File->Open or File->Save dialog inside of AutoCAD (or any other Autodesk product), there are a few items that can cause this:

  1. New HP Machine If you have recently purchased a new HP computer or you have an HP computer for which you have recently carried out an HP update on Windows 10, Windows 7, Windows 8 or Windows 8.1…Check if you have any of these applications installed:
    • HP Trust Center
    • HP Client Security Manager

      If so, uninstall them and reboot. We recommend you find an alternative as they cause this issue.

  2. For AutoCAD versions >= 2008, you can try disabling the InfoCenter toolbar at the top right of AutoCAD.
    1. If you know LISP, this code will work for all versions of AutoCAD 2008 or higher
      1. add this code to the end of your acad.lsp (vl-registry-write (strcat “HKEY_LOCAL_MACHINE\\” (vlax-product-key)”\\Applications\\InfoCenterAcConn”) “LOADCTRLS” 0)
    2. If you do not know LISP
      1. Start Regedit.exe
      2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\AutoCAD\<Release.Number>\ACAD-<VerticalCode>:<LanguageCode>\Applications\InfoCenterAcConn 
      3. Set the LoadCtrls value to 0
      4. To turn it back on, simply set LoadCtrls value to 76
  3. Remove all USB devices – older versions of AutoCAD don’t understand what a Samsung Phone is, and this can cause crashes.
  4. If you have been opening DWG files from your USB drive, try re-connecting the drive…
  5. The latest Windows Operating systems (Windows 10, Windows 7, Windows 8 and Windows 8.1) correctly use strict permission settings for your personal files (Documents folder etc). The problem is that your older version of AutoCAD does not understand these new permission settings, and this can cause AutoCAD to crash. As a quick test, copy the DWG files that always crash when you save to a USB drive, then create a new folder called c:\MyDwgs, now copy the files from your USB to the c:\MyDwgs folder. Finally, try AutoCAD with the DWG files in c:\MyDwgs – is AutoCAD working now? If so, you can either leave your DWG files in that folder, or you’ll need to relax the permissions on your DWG folder to allow access to AutoCAD.
  6. MSN Plugin – if you see MSN as an entry in your Windows Explorer, uninstall MSN – AutoCAD doesn’t like this.
  7. For versions of AutoCAD >= 2000i here’s a quick fix to bypass the problem (although hard to remember each time) – on starting AutoCAD, type “Options” at the command line, select the ‘Files’ tab, click ‘Browse’, then simply click cancel. Now cancel out of the Options dialog altogether. Try your File->Open… Does it work? If so, you should now be good until the next time you start AutoCAD.
  8. If you have a non-HP machine that is giving you this issue or (2) didn’t work for you, please record below in the comments section:
    1. What computer make you are running
    2. What specific Windows version you are running
    3. What exact version of AutoCAD you are running (e.g. AutoCAD Architecture 2008 32bit)
    4. What AutoCAD service packs (if any) you have applied
    5. What anti-virus software you are running. We’ll see if we can solve this for you…
  9. If all this fails, you can of course set FILEDIA = 0 at the command line to turn off the File Dialog User Interface

Rolling back to IE 10 from IE 11 in Windows 7, Windows 8 and Windows 8.1

If you are encountering licensing issues, blank screens or even crashing when launching AutoCAD it could be because you are using a version of Microsoft Internet Explorer which is not compatible with your version of AutoCAD… (If you are primarily seeing script errors, then first check out how to enable scripting support in IE 11)

Here is a list of AutoCAD versions that most likely will be affected…

  • AutoCAD 2005
  • AutoCAD 2006
  • AutoCAD 2007
  • AutoCAD 2008
  • AutoCAD 2009
  • AutoCAD 2010
  • AutoCAD 2011
  • AutoCAD 2012
  • AutoCAD 2013

It could be because you have Microsoft Internet Explorer 11 installed on your system. The solution is to rollback to Microsoft Internet Explorer 10, or maybe back as far as Internet Explorer 8. Here’s how:

 

Windows 7 users

  1. Click Start then Control Panel
  2. Once in Control Panel select Programs
  3. From Programs click Turn Windows Features on or off
  4. Once in the Windows Features dialog, simply un-check Internet Explorer 11 and click OK. You will be asked to reboot, which you should do. Once you reboot, IE 11 will have been rolled back to IE 10
  5. NOTE: If you are still having problems, you can repeat the process from (1) to (4) again in order to downgrade from IE 10 to IE 9 to IE 8. Autodesk products usually do not need further downgrading than IE 8, so if you are still having issues even with IE 8 then it’s most likely something else wrong on your system.
  6. NOTE: If you cannot downgrade far enough, your only option is to upgrade to 7.24  (or newer) of the Longbow Converter tool which now supports Internet Explorer 7 emulation mode

Windows 8 users

  1. Move your mouse to the bottom left corner of the screen, then right click your mouse and select Control Panel
  2. Once in Control Panel select Programs
  3. From Programs click Turn Windows Features on or off
  4. Once in the Windows Features dialog, simply un-check Internet Explorer 11 and click OK. You will be asked to reboot, which you should do. Once you reboot, IE 11 will have been rolled back to IE 10
  5. NOTE: If you are still having problems, you can repeat the process from (1) to (4) again in order to downgrade from IE 10 to IE 9 to IE 8. Autodesk products usually do not need further downgrading than IE 8, so if you are still having issues even with IE8 then it’s most likely something else wrong on your system.
  6. NOTE: If you cannot downgrade far enough, your only option is to upgrade to 7.24  (or newer) of the Longbow Converter tool which now supports Internet Explorer 7 emulation mode.

Windows 8.1 users

Window 8.1 comes with Internet Explorer 11 pre-installed and cannot be rolled back. Your only option is to upgrade to 7.24 (or newer) of the Longbow Converter tool which now supports Internet Explorer 7 emulation mode.
