Not sure if this is the correct place - I just installed 2020 Lacerte - it is a network install - like I have been doing for 20 years - when I go to open 2020 I get an error message:

DoBeforeInitialize: Exception - Error initializing config

Error updating proforma system files

EFCreateError: Cannot create file"C:\Lacerte\20tax\TMLTR1.ipo" The process cannot access the file because it is being used by another process.

I don't have anything else open or in use, i have rebooted twice and reinstalled.  Any suggestions?

Thanks!
