For each installation I always ran activate first then setup.
On the computer with the scanner connected I installed the 'server' version and the 'client' version. I tested a multi-page scan and it worked great. I didnt have any nag screens about registering. Although looking at Help About its not obvious that the software is registered.
I installed the 'client' version on two different computers (ran activate first) and I can successful connect to remote scanner and scan a multi-page document but the software is NOT registered. I have to select 'trial' to complete the scan. Please help me with registering the software. I will find it very useful!
