Cannot open file OpIndex.p5

Has anyone seen this error before? It is only happening on 1 workstation. I have verified, though, that the file does not exist on any workstation. 

 

We have tried uninstalling and reinstalling Lacerte 2025.

We have (per a Lacerte rep) tried using CLGRID to reset the Client Grid.

 

Error Message:

DoBeforeInitialize: Exception = Error initializing config.

Cannot open file “C:\Lacerte\25tax\20.10.7.0\OpIndex.p5”. The process cannot access the file because it is being used by another process.
