Summary

If GibbsCAM displays an error referencing LicenseKeyManager.dll or crashes while loading the ProAXYZ plug-in, the issue is typically caused by an incompatible or defective version of the Productec LicenseKeyManager.dll file.

This DLL is not included with GibbsCAM and is not developed or maintained by CAMCO. It is supplied by Productec as part of the ProAXYZ plug-in.

If the DLL is causing GibbsCAM to crash, removing it will typically resolve the issue. However, the ProAXYZ plug-in will no longer function until Productec provides a corrected version of the DLL.

Before You Begin

Before performing the troubleshooting steps:

  • Close all instances of GibbsCAM.

  • Verify whether your organization uses the ProAXYZ plug-in.

  • Administrator permissions may be required to modify files in the GibbsCAM installation directory.

Important: Removing the DLL disables the ProAXYZ plug-in until a replacement DLL is installed.

Procedure

Step 1 – Determine Whether ProAXYZ Is Installed

The LicenseKeyManager.dll file is installed only with the Productec ProAXYZ plug-in.

If your system does not use ProAXYZ, the DLL should not normally be present.


Step 2 – Locate the DLL

Browse to the GibbsCAM PlugIns folder:

C:\Program Files\Gibbs\GibbsCAM\<version>\PlugIns


Look for:

LicenseKeyManager.dll


Step 3 – Temporarily Remove the DLL

If GibbsCAM is crashing because of LicenseKeyManager.dll:

  1. Close GibbsCAM.

  2. Rename the file, for example:

LicenseKeyManager.dll.old


or move it to a temporary backup folder.

  1. Restart GibbsCAM.

Important: Renaming the file is recommended instead of deleting it, as it allows the file to be restored later if needed.


Step 4 – Verify the Results

If GibbsCAM launches successfully after removing the DLL, the Productec DLL is the source of the problem.

The ProAXYZ plug-in will not be available until a corrected version of the DLL is installed.


Step 5 – Contact Productec

Because LicenseKeyManager.dll is developed and distributed by Productec, CAMCO cannot provide updates or replacements for this file.

Contact Productec to obtain an updated version of the ProAXYZ plug-in or a replacement LicenseKeyManager.dll that is compatible with your version of GibbsCAM.

Expected Result

GibbsCAM launches normally without crashing. If ProAXYZ functionality is required, it can be restored after installing an updated LicenseKeyManager.dll supplied by Productec.
