Hello Velldanas,
I have looked in our Support page and cannot find anything on the issue you describe. At this point I would recommend calling Support for more assistance: 1-800-821-2797.
As title says, i have this issue. I have 2 accounts on PC. One is for administrator stuff. The second one is for regular user. Both are administrators. But the scan doesn't work on regular user account, which are administrator. Tried to reinstall drivers, doesn't work. The scan works only on administrator. Tried to create another user "TEST" with administrator rights and the scan works fine here too. Regular user have all rights. Any suggest ?
