I’ve had Avast A/V for quite awhile but when I upgraded to WindowsXP, it didn’t seem to work right. So I removed it from my pc (from the Control Panel’s ‘add/remove programs’) & downloaded it again today but when the download was completed, I opened the folder to install it but mysteriously the install box gave me only 2 options (instead of Install). It said to choose either the ‘CHANGE’ or ‘UNINSTALL’ so I am still not able to install my favourite antivirus… ???
I downloaded the English version & I am mystified as to what I’m doing wrong…please HELP!!! Thns & I’d love to know what I am doing wrong, please email me at:
LMstuart2@hotmail.com
because I will likely forget where I posted this LOL (not really) Thnx so much

- Use the unisttall util from the website to remove Avast.
- Reboot.
- Install Avast.
Does this solve the problem?

The reason it gave the Change and Install option was because it found a version of avast or something to indicate avast had been installed.
Avast Uninstall Utility, find it here:
As Eddy said you need to fully remove the old avast installation because it related to a different OS.

Eddy & David
Thnx for the quick reply. I tried David’s suggestion to go ‘here’ to uninstall but I got an ERROR 404-page not found. 
Eddy, I tried to uninstall thru my control panel/add-remove but I got this error msg:
avast!
A setiface (?) error has occured:2 Try to reinstall or contact support please.
Now what? Thns again too

Think David forgot to update that link when the new website was released.
HERE is the correct link.

If the utility does not work, you might have to go and manually remove all files and registry keys. The latter is a pain, so hopefully the utility works.
