Hi patmac,
Yes, please uninstall AAW SE Personal
before installing AAW 2007 Free.
To double-check which versions are on your system at present, first go to the Add/Remove Programs list - uninstall any showing there.
Then please download the Windows Installer Cleanup Utility (WICU) from
hereInstall and run the WICU (should be listed on your "Start > Programs" list) - it should detect any remaining installations of AAW. Highlight any that appear and then click remove.
Then double-check to make sure that the AAW SE files & folders have been removed from C:\Program Files\Lavasoft\Ad-Aware\ etc - any that remain may be manually deleted.
Regards,
Spike
