Can't get Avast 5 to install on Windows XP Home Edition
« on: September 24, 2010, 08:29:19 PM »
My aunt's PC was left to her older kids to run over the internet with no anti-virus software and is now totally infected. I have run Malwarebytes, Superantispyware and Glary Utilities to clean her system and that has done a good job. I installed Avast 5 free and when I try to run it I get this pop-up: "D:\Program Files\Alwil Software\Avast5\AvastUI.exe This application has failed to start because the application is incorrect. Reinstalling the application may fix this problem."

I have uninstalled Avast and tried reinstalling it but none of that works. The OS system is Windows XP Home Edition. Please help...

I have tried loading Avast on drive C but it still doesn't run. Gives the same prompt but for drive C. The reason I put it on drive D was because whoever got on my Aunt's computer partitioned out her system into 3 drives. Why? I have no idea? But most of my Aunt's programs are on the D drive.

not 100% sure but i think you need to install it on the same partition as the OS for it to work.....

No it can be installed on a different partition, but the registry is in the C:\ drive (or where the OS is installed). So given that the registry entries will be on C:\ it it really of little point in installing it on D:\ or any other partition. This is even more the case with avast5 as some of the information, etc. is stored on the C:\documents and settings or c:\Programdata folders depending on your OS.

I used to install programs on a different partition but if there is a problem on C:\ and you have to reinstall the OS the programs being installed on a different partition won't work as there will be no associated registry entries. So there really is little point in doing this as it doesn't achieve anything.

In looking closer at her system I can see that they set up the C drive as a backup drive and the D drive as the main drive that has the OS system, program files and all on it. They set up a third drive, drive E but it is empty. Could it be that there is still a hidden virus on the system that is stopping Avast from executing?
