Hello,
I am having great difficulty downloading and installing AVG 2012. Keeps on saying goodbye before installing and i am getting message that says MSI engine failed to install. Can't download. have tried 2 system restore points but still same.
 

Find an Installation Cleanup Utility and / or run MsFixit for installation errors.
A previous unsuccessful install or un-install has left remnants which are causing problems.
