If that does not work, or if you get a message saying something like "Can't find Install.log," perform a manual uninstall, which is not a very difficult procedure. Do the following:
1. Click on "my computer" and navigate to your Lavasoft Ad-Aware folder (C:\program files\lavasoft\ad-aware \
2. Run the file unregaaw.exe
3. Delete the entire ad-aware folder
4. Delete your Lavasoft Ad-Aware link in your start menu (if present)
5. Delete the Ad-Aware icon(s) from your desktop(if present)
6. Navigate to C:\Documents and Settings\[User Name]\Application Data\Lavasoft and delete the entire Lavasoft folder.
7. Empty your trash bin
8. Reboot.
