Pls verify that you are logged on as Administrator and that
no other related software are running such as Ad-Aware or ZoneLabs. It
would seem further that you would need to contact AVG / Grisoft and for
then to send you a batch file that you need to run before
installing AVG 8. The file is named "reset_access.bat
". After the bat
file, the installation should work. The bat file is supposed to clear up some permissions issue
that will allow the installation to proceed.
Alternately, you can Try downloading this files from this link
the zipped file (extract) to a folder in your C drive and run
reset_access.bat , it should fix the registry problem and allow
Or you can try manually editing your registry by deleting the entry HKLM\SOFTWARE\Classes\AvgDiagFile\DefaultIcon.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
