Uninstall & Reinstall F/X CAD or AutoCAD

You may need to uninstall an existing version of AutoCAD or F/X CAD on your computer because you are:

  • Installing a newer version, or
  • Fixing an issue with the software

Important: Are you uninstalling to fix an issue with a version of F/X CAD or AutoCAD that's older than the two most recent year versions? These older versions are considered "Legacy" and require a $50 fee for each re-installation. For more information, please see our Land F/X Scope of Support page.

Are you attempting to reinstall AutoCAD or F/X CAD to address a problem with the program? The Reinstall function, available within the Uninstall options, doesn't wipe out all your settings and can fix a number of issues. The Uninstall option is quite drastic and will remove personal settings. If you're trying to fix an issue with AutoCAD or F/X CAD, we highly recommend trying the Reinstall option before uninstalling and reinstalling.

Step 1: Uninstall all Autodesk products.

You may need to restart your computer to complete the uninstallation of some Autodesk products.

 

 

 

Step 2: Delete some specific Autodesk-related files and folders.

Once you've uninstalled all Autodesk products from your computer, you'll need to remove all files and folders that can potentially cause your computer to think a new AutoCAD or F/X CAD installation is still the previously installed version.

 

 

1. Open Windows Explorer by either:

  • Selecting Computer or This PC from your Start menu or
  • Selecting the folder icon in the taskbar in the lower left corner of your screen

 

 

 

2. Find and delete the following folders. You can delete each item by right-clicking it and then selecting Delete from the menu.

C:\Program Files\Autodesk\

C:\ProgramData\Autodesk\

C:\Program Files (x86)\Autodesk\

C:\Users\**YOUR USERID**\AppData\Roaming\Autodesk\

C:\Users\**YOUR USERID**\AppData\Local\Autodesk\

 

 

 

3. Open the Registry Editor, and delete any subkeys from the following registry items:

HKEY_CURRENT_USER\Software\Autodesk

HKEY_LOCAL_MACHINE\Software\Autodesk

 

 

 

4. Follow our steps to clear your temporary files.

 

 

 

5. Restart your computer.

 

 

 

6. If you need to reinstall AutoCAD or F/X CAD, make sure your antivirus or security software is turned off when you reinstall. You can turn it back on once you've completed the installation.

 

 

 

 

AutoCAD or F/X CAD 2016 or older

1. Open Windows Explorer by either:

  • Selecting Computer or This PC from your Start menu or
  • Selecting the folder icon in the taskbar in the lower left corner of your screen

 

 

 

2. Delete the files and folders listed below. You can delete each item by right-clicking it and then selecting Delete from the menu.

 

You'll need to turn on your hidden files and folders to see many of the files and folders listed below.

 

 

 

3. Find and delete the following items:

The installation folder for every Autodesk product you've had on your computer. Examples include:

  • C:/Program Files/F/X CAD 20xx or
  • C:/Program Files/Autodesk/AutoCAD 20xx

 

 

 

The folder named C:/Program Files/Common Files/Autodesk shared (The location of this item may vary depending on where you had AutoCAD or F/X CAD installed.)

 

 

 

Any user profile folders (substitute your login name for username):

  • C:/Users/username/AppData/Roaming/Autodesk/AutoCAD 20xx
  • C:/Users/username/AppData/Local/Autodesk/AutoCAD 20xx
  • C:/Program Data/Autodesk/AutoCAD 20xx

 

All Autodesk backup files in the folder C:/ProgramData/FLEXnet

  • Delete all files in this folder whose filenames start with adsk

 

 

 

Having trouble finding the files and folders listed above? You can search for them using the Windows Explorer search box:

 

Don't forget to turn off your hidden files and folders once you've deleted all the necessary items.

 

4. If you need to reinstall AutoCAD or F/X CAD, make sure your anti-virus or security software is turned off when you reinstall. You can turn it back on once you've completed the installation.

 

 

 

For more information on uninstalling Autodesk products, see the official Autodesk article on the subject.

Step 3: Run a disk cleanup.

Running the Disk Cleanup utility will ensure that you've removed all cached AutoCAD installers from your computer.

 

3A. Open your Start menu, and search for Disk cleanup in the search box.

 

Select Disk Cleanup from the list of results.

 

 

 

3B. The disk cleanup utility will scan your computer. The Disk Cleanup dialog box will open.

 

Click Clean up system files.

You'll see a number of files listed under Files to delete, but you can ignore this list for now and click Clean up system files.

 

 

 

3C. The Disk Cleanup utility will scan your computer again. The Disk Cleanup dialog box will open again.

 

Select the file types to delete from the Files to delete list. We recommend checking all these options. At the very least, make sure the Temporary files and Temporary Windows installation files options are checked.

To see a description of a file type, just select it.

 

Click OK. The Disk Cleanup utility will delete all cached installer files.

Having trouble removing any parts of the software? Use the Microsoft FixIt Tool to remove any components that are giving you trouble.

Step 4: Restart your computer & reinstall CAD (if necessary).

Restart your computer. You've now successfully uninstalled existing versions of F/X CAD or AutoCAD.

 

If you need to reinstall F/X CAD or AutoCAD, you can do so at this time.

Problems installing? You may need to disable your antivirus software temporarily while installing AutoCAD or F/X CAD. Don't forget to enable it once the installer finishes.

Moving from AutoCAD to the same year version of F/X CAD? Do this too.

If you're moving from the same year version of AutoCAD to F/X CAD – for example, from AutoCAD 2020 to F/X CAD 2020 – you'll also need to download and run the A/X CAD Activation Patch.

 

With F/X CAD closed, right-click the link below and select Save link as or Save target as from the menu. Then save the link to a location where you can locate it easily, such as the desktop.

 

 

Locate and run (double-click) the downloaded file named FXCADActivationPatch.exe.

 

You can now open F/X CAD and begin working.
