Controlled folder access blocks applications from writing to your Documents, Pictures, Videos, Music, Public and Favorites folders. AutoCAD versions all the way to AutoCAD 2021 write to certain user Public folders and are therefore blocked by this feature. This can cause issues with all sorts of things including activating your AutoCAD license and even running AutoCAD. Ransomware Protection is an important feature of Windows 11 but it will affect your AutoCAD unless you allow AutoCAD and its dependent applications access to the controlled folders.

Ransomware Protection Windows 11 and AutoCAD

Just before we start note that Windows 11 comes with a Ransomware Protection which includes Controlled Folder Access. Controlled folder access blocks applications from writing to your Documents, Pictures, Videos, Music, Public and Favorites folders. AutoCAD versions all the way to AutoCAD 2021 write to certain user Public folders and are therefore blocked by this feature. This can cause issues with all sorts of things including activating your AutoCAD license and even running AutoCAD. Ransomware Protection is an important feature of Windows 11 but it will affect your AutoCAD unless you allow AutoCAD and its dependent applications access to the controlled folders.

How to install AutoCAD R14

A quick word of advice: please follow the instructions below precisely as documented including using the same folder names and paths. This will significantly reduce the risk of having any problems…

    3. Using the “. . .” button, select your AutoCAD R14 installation CD
    4. Next, click the “Run Old Installer” button and follow the onscreen instructions. If all is well a dialog will appear stating success, simply click OK to start your AutoCAD setup
      1. Now I know it’s unheard of these days, but at this point expect to wait up to 45 minutes for your AutoCAD R14 setup.exe program to appear, be patient – NOTE: do not continue with the install until reading the next step…
    5. Once the setup starts, stop and read the next steps all the way to the end! By the way, if your AutoCAD R14 setup does not start after 45 minutes, read the Troubleshooting section below.

  3. In the AutoCAD R14 setup program…
    1. navigate through each setup dialog as normal, with these exceptions…
      1. Make sure you do a Typical Install (not a Full Install)
      2. When you get to the installation folder input dialog **it’s vitally important to make sure you install to c:\acadR14 (not Program Files\AutoCAD R14 as usually prompted)**
You must change the install path to c:\acadR14
  1. Now carry on with the install
    1. Do not reboot once the install is complete
    2. Ignore any errors related to not being able to create the shortcut e.g. “Cannot Create folder ‘AutoCAD R14’“, you will have to create a shortcut on your computer Desktop to your c:\acadR14\acad.exe by hand.
    3. Again, do not reboot if prompted to do so
  2. Once your AutoCAD R14 setup has completed the installation…
      1. Make sure you fully close the setup program.

    2. 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 R14 from Windows Safe Mode
  2. If you are getting either a Bad Mem Pointer error and or a Smartheap handler recursively re-entered error when you start your AutoCAD R14 then you need to re-run all the steps above, taking care to do each step precisely as it says, most likely you are missing from step 5 or you have not installed to c:\acadR14 as stated in step (7) above.

This error can happen if you upgrade your Windows version (say Windows 7) to Windows 10 without first removing your AutoCAD install. Check out this post where we talk about how to correctly upgrade your AutoCAD to Windows 10

If you are hitting this error:

  • try installing your AutoCAD’s latest Service Packs/Updates
  • add all application exe’s to your anti-virus Exclusion list

If that doesn’t solve the issue then most likely you will have problems remedying because even an uninstall/reinstall doesn’t solve the problem.

Error: “Please install DirectX before installing AutoCAD”

Posted on by

While installing AutoCAD you may run into a blocking issue whereby the DirectX runtime (which AutoCAD relies upon for its hardware 3D capability) fails to install for some reason (Error 1603). Solutions posted on Autodesk website show how to edit the setup.ini file to try and solve this issue, however, upon doing so you get a new error, for instance…

“Error: Please install DirectX before installing AutoCAD MEP 2013”

You can easily solve this issue (and others) by installing your AutoCAD using the Longbow Converter App. It manages the install and bypasses all issues like these automatically so you can be up and running again. You will need V11.19 or newer of the Converter App). But be aware of these caveats:

  • The Converter will allow you to ignore the DirectX failure and allow AutoCAD to correctly install, but DirectX won’t be installed. This means that:
    • 2D will work fine
    • 3D will fine, but only in Software mode (slower)
    • Everytime you start AutoCAD you will get a Heidi error, like this one…

      “…the configured heidi driver cannot be loaded…“

      to stop this, in AutoCAD, right click the Command Line->Options->System->Graphics Performance->HardWare Acceleration: Turn off

Why run 32bit AutoCAD on 64bit Windows

Posted on by

AutoCAD versions pre 2008

AutoCAD R13 | AutoCAD R14 | AutoCAD 2000 | AutoCAD 2000i |AutoCAD 2002 | AutoCAD 2004 | AutoCAD 2005 | AutoCAD 2006 | AutoCAD 2007

Users of these really old AutoCAD versions have literally been using them for decades and moving to a new version of AutoCAD is extremely disruptive for them. Being able to use old versions of AutoCAD on new versions of Windows restores efficient workflows and concepts.

Old versions of AutoCAD only come as 32bit

AutoCAD versions starting back in the 90’s like R13, R14, 2000, 2000i, 2002, 2004, 2005, 2006 and 2007 only come as 32bit applications. Our Longbow Converter solution we can make them run like new on the latest versions of 64bit Windows.

Solve AutoCAD installation error messages

  • Wrong OS. AutoCAD supports Windows NT 4.0, Windows NT 5.0, Windows 95 and Windows 98
  • This app cannot run on your PC

These blocking AutoCAD setup issues are completely solved by using our Longbow Converter solution.

Significant 3rd Party ObjectARX, VBA, VB6 investment

Some users can also run into issues where they have significant investments in 3rd party ObjectARX, LISP, VBA or VB6 applications that only run on their existing version of AutoCAD.

Our Longbow Converter solution allows them to be installed alongside these old versions of AutoCAD once again.

AutoCAD Versions post (and including) 2008

AutoCAD 2008 | AutoCAD 2009 | AutoCAD 2010 | AutoCAD 2011 |AutoCAD 2012 | AutoCAD 2013 | AutoCAD 2014 | AutoCAD 2015 | AutoCAD 2016 | AutoCAD 2017 | AutoCAD 2018 | AutoCAD 2019

Solve blocking AutoCAD installation error messages

Users of these versions of AutoCAD are generally restricted from installing their AutoCAD with messages like

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

All solved by using our Longbow Converter solution…

Reliability

Our users have consistently reported to us that 32bit AutoCAD is more reliable than the 64bit version, especially in the early releases (2008 to 2013ish). We think this might be because AutoCAD was originally a native 32bit program for which Autodesk ported to 64bit. It’s true, 32bit AutoCAD can’t load in DWG files larger that 2GB but we added a feature to our Longbow Converter solution that allows 32bit AutoCAD to load up to a 4GB DWG file.

In addition, being a legacy 32bit application, 32bit AutoCAD is less targeted by Windows Update making it much more reliable against those annoying updates.

Slow VBA Performance

Other users are impacted by severe performance issues when running their VBA code on 64bit AutoCAD. You may not even be able to run your VBA code on 64bit AutoCAD. This is because AutoCAD VBA runs in a completely separate executable (exe), away from AutoCAD on 64bit Windows, making it almost 1200 times slower than AutoCAD VBA running 32bit AutoCAD. Installing 32bit AutoCAD solves the problem and restores performance… This issue is solved by using our Longbow Converter solution.

Significant 3rd Party ObjectARX, LISP, VBA, VB6 investment

Some users can also run into issues where they have significant investments in 3rd party ObjectARX, VBA or VB6 applications that only run on their existing 32bit version of AutoCAD.
