Uninstall without system restore?

Recommended Posts

I've been an ad-aware user for quite awhile.


I wanted to upgrade to Ad-aware 10.5, but the installation kept failing:

"Ad-Aware had encountered an error during the installation"


So I decided to uninstall 10.4, and I am getting error 1722.


I've made alot of important changes to my computer in the past couple of months, and I really need to avoid rolling ALL of them back just because of one program.


What are the more practical options?

DKielby wrote a good description of how he/she solved the problem:

First I looked in the Programs and Features control panel. I found three Ad-Aware installations.

1. Ad-Aware Security Add-on v2.2.0.11

2. Ad-Aware Browsing Protection v1.0.1.41

3. Ad-Aware Antivirus v10.2.21.3698


I successfully uninstalled the Security Add-on. I successfully uninstalled Browsing Protection. Then, the Antivirus program which remained offered two choices; 'CHANGE' and 'REPAIR'. There was no option to uninstall. I did not even look at the CHANGE option. I ran the REPAIR option. The repair process did it's thing and disappeared.


Try that before you uninstall Ad-Aware Antivirus.

Yea, I was also able to uninstall the browser protection (didn't have the security add-on), but the regular ad-aware still won't go away.


The repair functions works (at least it doesn't report an error), but I don't know what its actually reparing :S i still get the same error. I can't install 10.5 and i can't uninstall 10.4


windows is saying that it had a "fatal error during installation." this is making me sad

Then it might be a problem with the MSI installer in Windows. Please, run Fixit tool from Microsoft: http://support.microsoft.com/mats/Program_Install_and_Uninstall

Uninstall Ad-Aware before trying to install the new version.


Edit: If that doesn't help, please specify which Windows you have.
