GLSU Excel add-in fails to load after Office update from Version 2607 to 2608

Hello vrushalipawale​,

This points to a VBA compatibility issue in the add-in rather than a general Excel macro issue.

Microsoft documents that “Compile error in hidden module” can occur when VBA code in a protected module cannot compile, including cases where the code is incompatible with the Office version or architecture.

Since the issue started after the update from Version 2607 to 2608, I would check:

• Whether a newer GLSU/Process Runner version is available.
• Whether the affected machines use 32-bit or 64-bit Office and whether the add-in supports that architecture.
• Whether the issue occurs with Excel started in Safe Mode.
• Whether the same add-in works on Version 2607 but fails on Version 2608.

The “Cannot run the macro 'onLoad'” and “Compile error in hidden module: ThisWorkbook” messages also point to the add-in's VBA project failing during its startup process.

Microsoft's documentation on this error:
Compile error in hidden module: <module name>

Because the failing code belongs to the third-party GLSU add-in, the vendor should also confirm compatibility with Office Version 2608.
