Try uinstalling it in safe mode. If that also works try this. Install Mandriva Linux 9.1 or
higher. You can access all Windows partitions , including NT partitions. To access C
drive type '/mnt/win_c' in Konqueror(KDE). Go to the folder where American Army is
installed and delete it!! That's all it will get deleted 100%. ZoneAlarm Pro used to
give me the same problems, and I deleted it this way!!
enter safe mode
install the game again in the same folder.
then try to uninstall it.
u may have to reboot...
if it dznt work, again go to safe mode and delete all the programs folder.
then use a good junk/registry cleaner to clear pc junk.
try this one www.ccleaner.com
u can also use it to remove invalid entries from ur 'addremprogs'.
