I've been trying for over a month to install AVG Antivirus on my new Windows 10 machine. I've tried every suggestion on this site to fix my issue and it continues to fail on install. I'm getting the same error as everyone else (ends in 643 I think). I've run the AVG remover program, cleared everything off my hard drive, and still it continues to fail on install. I've taken other people's posts in regard to this error and followed the tech suggestions step-by-step. This is the most frustrating software install that I've ever encountered on any computer that I've owned. Can you please help?
