We have just discovered a bug in Ad-Aware 2007 that is caused by an update to IE7 and that may be what you are encountering. We are working on a resolution, but meantime an update to the new version 2008 does resolve the problem for most. I am told deleting the Ad-Aware Folder in Program files/Lavasoft will get around the uninstall issue you had.
Please try to uninstall Ad-Aware 2007 and if you get an error, look for the following folder and delete it:
C:\Program Files\Lavasoft\Ad-Aware
Then proceed to install Ad-Aware 2008 and let us know if that resolves the problem?
I had/have a similar problem...while attemting to update Ad-Aware 2007 version 7.0.2.7...on XP with IE6
I got...unhandled exception aawservice.exe has unfortunatly experienced an unhandled excption and was
forced to close. Please submit this error and we will endeavor to solve the problem as soon as possible. After
submiting the error...a dialog box came up...system error 1810 has occurred. Description Service is not online
application terminates. Well I was online....Your products are great...but I WISH YOU HAD NOT STOPPED
AUTOMATIC UPDATES FOR...Ad-Aware SE Personal...it still catches critical objects that 2007 misses...and it
is 359 days since it's last update...anyway keep up the great products...and please get this unhandled exception fixed
THANKS VERY MUCH...gamer8
