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 an external drive (e.g. USB drive) try re-connecting the drive…
  5. The latest Windows Operating systems (Windows 7, Windows 8, and Windows 10) correctly enforce 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 stop you being about to open your DWG files and even cause AutoCAD 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. Check out this page Interactions with the AutoCAD Ribbon crashes AutoCAD on Windows 10
  10. If all this fails, you can of course set FILEDIA = 0 at the command line to turn off the File Dialog User Interface

Installing Softdesk 8 for AutoCAD R14 on Windows 10, Windows 7, Windows 8 and Windows 8.1

Posted on by

NOTE: We have had the best success installing this product using our Converter solution on Windows 8 and Windows 10

Installing your Softdesk 8 for AutoCAD R14 on Windows 10, Windows 7, Windows 8 or Windows 8.1 32bit or 64bit can be very easily defined in these short steps.

A quick word of advice: best to follow the instructions below precisely and to the letter, including folder names and paths, that way you will reduce the risk of having any problems…

  1. First, obtain your copy of the Longbow Converter here
  2. Install your AutoCAD R14 by carefully following the steps detailed here
  3. Using Windows Explorer, copy your entire Softdesk CD to your hard drive, to a folder path c:\Autodesk\softdesk
  4. Start the Longbow Converter tool, select the 2nd tab, pick the c:\Autodesk\softdesk folder, and click Run. Read and understand all the prompts before pressing OK. Now, I know it’s unheard of these days, but at this point expect to wait at least 45 minutes for your Softdesk setup.exe program to appear. Once the setup starts, install as normal (simply accept all defaults).
  5. Next we need to initialize Softdesk on startup, so depending on what works best for you – either
    1. Start your AutoCAD R14 by running c:\acadR14\acad.exe. Once AutoCAD starts up fully, simply type preferences at the command line, select the Profiles tab, double click the Softdesk profile and make it the Current Profile. Finally, OK out of the preferences dialog.
    2. Another way to intialize Softdesk on startup is to create a Desktop shortcut to c:\acadR14\acad.exe – make sure the shortcut
      1. Target: is set to C:\acadR14\acad.exe /c c:\sdsk\programs /p “softdesk 8” 
      2. Working Directory: is set to C:\acadR14
  6. Now you can happily run your Softdesk tools inside of AutoCAD R14 on Windows 10, Windows 7, Windows 8 or Windows 8.1 32bit or 64bit

Troubleshooting

If your setup is not starting after 45 minutes, try rebooting, then restart the steps above.

  • If it is still failing, most likely it’s because of another application on your system which is preventing our setup routine from starting (perhaps anti-virus, or similar) – try installing from Windows Safe Mode

  5. Now carry on with the install (do not reboot once the install is complete) Ignore any errors related to not being able to create the shortcut, you will have to create a shortcut on your computer Desktop to your c:\mdtR14\acad.exe by hand. You will also be prompted that Adobe reader needs to be installed – when you press OK, expect to wait at least 45 minutes for the Adobe setup.exe program to appear install as normal accepting all defaults this time.
    1. Do not reboot if prompted to do so…
  6. Once installed, go back to the Converter tool, select the 3rd tab, pick the newly installed c:\mdtR14 folder and click Fix.
  7. Now you are ready to run AutoCAD, simply run c:\mdtR14\acad.exe using Windows Explorer.
  8. You will notice that you are running raw AutoCAD, to enable your Mechanical Desktop features, carry out these next steps…
    1. At the AutoCAD Command line, type the command ‘Preferences’, add new Support path folders c:\mdtR14\acadm and then also c:\mdtR14\acadm\support, now click ‘Apply’ and then ‘OK’ out of the dialog.
    2. Next, restart AutoCAD.
    3. When you are back in AutoCAD, type ‘Menuload’ at the command line, click browse, then navigate to C:\mdtR14\acadm\support, change the file filter at the bottom to *.mnu, then open acadm.mnu, finally click Load, then pick Close.
    4. Now restart AutoCAD
  9. Now you can happily run your Mechanical Desktop Release 2.0 on Windows 10, Windows 7, Windows 8 or Windows 8.1 32bit or 64bit

    2. When you arrive at the installation folder path setup dialog, **it’s vitally important to make sure you install to c:\civil3d2007 (not C:\Program Files (x86)\Autodesk Civil 3D 2007 that is defaulted)**.
    3. If asked to reboot after the install, say NO
  5. Once installed, do not reboot, make sure you fully close the AutoCAD setup program (because the Converter is waiting for the setup program to fully close) then go back to the Converter tool, select the 3rd tab, pick the newly installed c:\civil3d2007 folder and click the Fix Old Program button.
  6. Now you can run your Autodesk Civil3d 2007 on Windows 10, Windows 7 and Windows 8, both 32bit and 64bit.

AutoCAD 32bit/64bit side-by-side installation compatibility chart

Posted on by

This blog has been written to help advise those who require 32bit versions of AutoCAD to reside on the same computer system as 64bit versions of AutoCAD.

Before we start, when installing 32bit AutoCAD on 64bit Windows, you should take care not to mix the same version/series of AutoCAD 32bit with the same version/series of the corresponding 64bit version of AutoCAD, on the same computer. The reason is that they were not designed to run in a side-by-side configuration and therefore may conflict. The same rule can generally be made for all Autodesk products.

NOTES:

  • When installing 32bit AutoCAD, we advise that you uninstall all previous versions of 64bit AutoCAD before installing your 32bit version of AutoCAD.
  • If you are installing multiple versions of AutoCAD, you should always install in chronological order, in other words, oldest to newest.
    • e.g AutoCAD 2004, Architecture 2004, Map 2005, AutoCAD 2007, Civil3d 2015
    • Failure to follow this simple rule can render you with missing entry point errors, un-explained crashing, un-installable Autodesk software and more.
  • For best results, we recommend that you install only 32bit versions of AutoCAD on your computer system, however, mixing is possible with care – refer to the chart below if you must have the 64bit version installed on the same computer.

This chart shows which 32bit AutoCAD versions can be installed on the same system as 64bit AutoCAD versions…

  • Green means Should be OK
  • Red/Dark Red means Problems will occur, you should not do this
