Ransomware Protection Windows 11 and AutoCAD
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.

Once installed, start the Longbow Converter App…
Now place your AutoCAD LT98 CD in the CDRom Drive
In the Converter App, select the 2nd tab named “Old AutoCAD Installer Reviver“
Using the “. . .” button, select your AutoCAD LT98 installation CD
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
Now I know it’s unheard of these days, but at this point expect to wait up to 45 minutes for your AutoCAD LT98 setup.exe program to appear, be patient – NOTE: do not continue with the install until reading the next step…
Once the setup starts, stop and read the next steps all the way to the end! By the way, if your AutoCAD LT98 setup does not start after 45 minutes, read the Troubleshooting section below.
In the AutoCAD setup program…
navigate through each setup dialog as normal, with these exceptions…
Make sure you do a Typical Install (not a Full Install)
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)**
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 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.
Again, do not reboot if prompted to do so
Once your AutoCAD LT98 setup has completed the installation…
Make sure you fully close the setup program.
Once the setup is closed the Converter will automatically fix the c:\acadlt98 program files. You should see “Success!” displayed in the 3rd tab named “Old AutoCAD Program Reviver“
Now reboot your PC
You can now run your AutoCAD LT98 as normal, using Windows Explorer, navigate to c:\acadlt98 and double click aclt.exe
Troubleshooting
If your AutoCAD LT98 setup is not starting after 45 minutes…
First try turning off UAC, 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 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
Using the “…” button, pick your acad.exe folder e.g. c:\acadlt98

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.
