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 ADT 2000

- If you don’t yet have a copy of the Longbow Converter App you can purchase it here or click on the download link we sent you via email in order to download the Converter App to your PC.
- Before installing the Converter App, make sure the files downloaded from our site are not blocked by Windows SmartScreen… Windows 11 is finicky, click the TLC zip first to make sure it’s fully selected then Right+click the file and select Properties. Be sure to check the Unblock checkbox as shown below and Click OK…
- Double click the zip file to open it and install the TLC application as normal. By the way, TLC stands for The Longbow Converter

- For AutoCAD ADT 2000, the Migration Wizard almost instantly pops up
- simply click “Install….” as normal.
- Now, I know it’s unheard of these days, but at this point expect to wait at least 45 minutes for your AutoCAD ADT 2000 setup.exe program to fully appear – please be patient
- Once the setup starts, stop and read the next step…
- In the setup program, navigate through each setup dialog as normal, except when you get to the installation folder **it’s vitally important to make sure you install to c:\adt2000 (not Program Files (x86)\AutoCAD Architectural Desktop as usually prompted)** e.g.
- Once you have set the Destination Folder to c:\adt2000, install as normal by selecting the Typical install
- Ignore the error message that the shortcut cannot be created “Cannot create folder AutoCAD Architectural Desktop” you will need to create the program shortcut by hand once the installation is finished.
- Do not reboot if prompted to do so
- Once setup has completed…
- Make sure to fully close the setup program
- Back in the Converter App…
- make sure it has completed the final stage of processing using the “Old AutoCAD Program Reviver” tab – it should display “SUCCESS” in green…
- Now Reboot your PC
- Your AutoCAD ADT 2i is ready to run as it is right now, simply use Windows Explorer, navigate to c:\adt2000 and double click acad.exe (if you want a shortcut on the Desktop you will have to manually create it)
