Hi Amy,
Did you used offline package for clean installation, after removing AVG?
Thanks

Have done that.  Removed AVG completely using removal tool, re-downloaded, and attempted reinstall.  Same error

Was prompted to upgrade my AVG Free 2014, so attempted.  Now I get:

Severity: Error
Error code: 0xC0070643
Error message: General internal error
Additional message:  MSI Engine: Failed to install the product.
Contect: AVG Product installation, MSI action failed.

Amy, Re Zbynek's posting it's referring to Part C in the article. If you're not sure about 32 or 64 bit on your system have a look @ this link (http://forums.avg.com/ww-en/avg-free-forum?sec=thread&act=show&id=140471#post_140471).
