Installation Failed

Hi William,
Try reinstall AVG using package downloaded from AVG MyAccount.
Thanks

I currently have AVG 2015 Anti Virus downloaded on my computer (Windows Vista).  I just purchased the AVG 2015 Performance from a local retailer.  When I try to download the new disc, I get an error message stating installation failed.  Then I keep getting a message from AVG to purchase AVG Performance or try the 30 Free Trial of Performance.  Any suggestions?
