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 LT 98

Be sure to check the Unblock checkbox as shown below and Click OK…
  1. Double click the zip file to open it and install the TLC application as normal. By the way, TLC stands for The Longbow Converter

    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:\acadlt98 (not Program Files\AutoCADLT98 as usually prompted)**
  4. 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 LT98’“, you will have to create a shortcut on your computer Desktop to your c:\acadlt98\acad.exe by hand.

Troubleshooting

  • If your AutoCAD LT98 setup is not starting after 45 minutes…
    1. First try turning off UAC, rebooting, then restart the steps above.
    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 LT98 from Windows Safe Mode
  • If you are getting either a Bad Mem Pointer error and or a Smartheap handler recursively re-entered error when you start your AutoCAD LT98 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:\acadlt98 as stated in step (7) above.
  • When starting AutoCAD, if you receive an ‘acad.exe – System Error’ message: The program can’t start because ac1st15.dll is missing from your computer. Try reinstalling the program to fix this problem. If you carried out step (7) above, then try rebooting your PC
  • If you are getting a WinHelp() error when pressing F1 to try and access the Help system then simply install the WinHelp (WinHlp32.exe) module from Microsoft
  • Issues with Calcomp Digitizer – Calcomp Digitizer not working
  • If the setup displays an error message InstallError (IUO)               
    (X)  not enough space(IUO) try unplugging any External USB drives
  • Plotting issues? If you get an error splwow64.exe “The application was unable to start correctly” with error “0xc0000005”
    1. Make sure your Anti-virus and/or Windows Firewall is not blocking splwow64.exe
    2. If the problem persists
      1. First, note that you need the latest version of the Converter App
      2. Start the Converter App
      3. Select the 3d tab “Old AutoCAD Program Reviver” 
      4. Click the Tools Menu->Reduced Power Mode

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
