Before You Begin

Before performing the troubleshooting steps:

  • Save and close all open GibbsCAM sessions.

  • Ensure all instances of GibbsCAM are completely closed before running the Recovery Tool.

  • Administrator permissions may be required to reinstall the software.

Procedure

Step 1 – Close All Instances of GibbsCAM

Before attempting any repairs:

  1. Close GibbsCAM.

  2. Verify that no GibbsCAM processes remain running in Windows Task Manager.

Running the Recovery Tool while GibbsCAM is open may prevent it from repairing all required files.


Step 2 – Run the Recovery Tool

The Recovery Tool resets GibbsCAM user settings and repairs common configuration issues.

  1. Open the Windows Start menu.

  2. Launch the Recovery Tool for your installed version from the Windows Start menu.



    Alternatively, run the tool directly from:
    C:\Program Files\Gibbs\GibbsCAM\<version>\Bin\Recovery Tool.exe



  3. Allow the process to complete.

  4. Restart GibbsCAM.


Step 3 – Perform a Clean Reinstallation

If the error continues after running the Recovery Tool, perform a complete reinstall.

  1. Close GibbsCAM.

  2. Delete the User Preferences folder:

C:\Users\<username>\AppData\Roaming\Gibbs\GibbsCAM\<version>


  1. Uninstall GibbsCAM using Apps & Features or Programs and Features.



  2. Restart the computer.

  3. Temporarily disable antivirus or endpoint security software if permitted by your organization's IT policies.

  4. Reinstall GibbsCAM.

Important: Do not run the Migration Tool after reinstalling until you have confirmed that GibbsCAM launches normally. Migrating previous settings may restore corrupted configuration files.


Step 4 – Test GibbsCAM

Launch GibbsCAM after reinstalling.

If the application opens normally, verify that the error no longer occurs during normal operation.

Expected Result

GibbsCAM launches and operates normally after repairing or reinstalling the application.
