I have a users that have two seat licenses and are both setup as multi user mode. My one user (the admin) is having trouble getting onto Quickbooks if the other user logs on first.
The admin user has a 32 bit Windowz 7 PC and the other user has a 64 bit Windows 7 PC. If my user logs on first and then my admin use I get the attached message and it blocks out my admin user. However if my admin user gets on first and then the standard user it will allow both on.
I downloaded the Diagnostic Tool, followed the instructions to clear the fire wall but still receive the message.
If you require more independence (anyone can access anytime) then you need to do the following:
1. On the admin machine, turn off "Host Multi User Access"
2. Move the company data file (ledger) to a server location.
3. Install the server manager (QB DVD) on that server location.
4. Scan for the ledger.
Then either user should be able to access the file with this second method.
The two methods (a) Host Multi User Access and (b) Server location and different from each other and use only one. If the first way is working, it is set up properly.
