I had AVG 8.5 and was reminded to upgrade and have had trouble doing so.
I am running windows XP with service pack 3
-On initial download it would not recognize internet connection.
-A reinstall claimed problem with Registry
-Went to forum and was advised to run AVG uninstaller program which I did
-retried install and still no luck... Error code 0XE001C04E
Now I have NO protection at all as the uninstaller unistalled 8.5 as well as remnants of 9.0
PLEASE HELP ME GET PROTECTED
