    Updated on: May 13, 2026

    Issue

    A restart is required to update required Autodesk components for this installation, please save any work then click OK to continue or Cancel to exit the installation.

    A restart is required error message

     

     

    Cause

    The Autodesk Identity manager installation is damaged or corrupted, which is causing the error.

     

     

    Solution

    1. Restart your computer. In most cases, restarting will correct the issue, and you can continue installing F/X CAD.

    Do you keep seeing this message after restarting your computer? If so, move on to the next steps.

     

     

    Windows Start menu showing Add or remove programs option

    2. Open the Windows Start menu, and type Uninstall in the search bar.

     

    Select the Add or remove programs option from the menu.

     

     

    3. Look for Autodesk Identity Manager in the list of applications.

     

    If you see it listed, click the ... button to the right, then select Uninstall from the menu that opens.

    Autodesk Identity Manager in list of applications

    Don't see Autodesk Identity Manager in the list of applications? Or are you unable to uninstall the Autodesk Identity Manager in the list? Open the Windows File Explorer and navigate to the location C:\Program Files\Autodesk\AdskIdentityManager\.

     

    Right-click the file Uninstall.exe in this location, then select Run As Administrator from the menu that opens.

     

    Running the file Uninstall.exe as an administrator from the location C:\Program Files\Autodesk\AdskIdentityManager\

     

     

    Follow the prompts to complete the uninstallation process.

     

    Is the AdskIdentityManager folder empty? Or do you not see the Uninstall file in that folder? Here's what to do..

     

     

    4. Restart your computer.

     

    5. Install F/X CAD again. You should now be able to install without seeing the error.

     

     

    Unable to uninstall the Autodesk Identity Manager? Don't see any files to uninstall in the Autodesk Identity Manager folder? Here's what to do.

    If you were unable to uninstall the Autodesk Identity Manager from the list, and/or you don't see any files to uninstall in the Autodesk Identity Manager folder, the issue is likely stemming from leftover registry keys from the Autodesk Identity Manager that also need to be uninstalled. Here's how.

     

    1. Download and install the Revo uninstaller.

     

     

    2. Open Revo. Right-click the Autodesk Identity Manager entry in the list of applications, then select Uninstall from the menu that opens.

    5. You'll see the message Performing the initial analysis and uninstall. Click Scan.
