Invalid Update Control CTF File AVG 8.0 Error on Vista

By | November 1, 2008

Since the 24th October I’d been getting the error “Invalid Update Control CTF File” when trying to update AVG 8.0 on my home PC.  I think I remember having this before and it went away after a few days, so I had been ignoring it until today.

Anyway, I found two control files for AVG in the folder “C:\ProgramData\avg8\update\download”, as shown below


I simply renamed them both and then selected “Update Now” after right-clicking the AVG icon on the application tray. 


The update applied successfully and now all is well.  🙂
