I have WinXP SP3 32bit and AVG2011 installed. I never had problems since today. AVG wanted to update but at the last step (finishing update), I get an error message "Update Failed, Invalid Binary Update file" and updating stops. I was looking for a solution and read some posts in this forum, but all I tried, nothing worked, neither deleting temporary update files, nor a reinstall.
AVG User Interface says that I'm fully protected and all functions are up to date, but it can't be right because when I want to update manually, there is one file and download and installation of this file works perfectly, but because of "Invalid Binary Update File", it can't be finished.
Unfortunately I don't know how to make log files of the failed update.
