After installing Studio v3.8 they have 1 server & 8 user licenses. They have just four devices that can connect. The fifth device errors 'User Limit Reached'.
Solution: Before doing this step ,you may want to contact support, if you have not worked with the registry.
The issue was resolved by editing the registry.
The licenses are being stored under:
\HKEY_LOCAL_MACHINE\Software\Wow6432Node\Point Information Network, and \HKEY_LOCAL_MACHINE\Software\Wow6432Node\Point Information Network, Corp.
The customer will need to export the registry, change the path to:
\HKEY_LOCAL_MACHINE\Software\Point Information Network, and
\HKEY_LOCAL_MACHINE\Software\Point Information Network, Corp
then import it back in the registry.
The "Point information Network, and Point Information Network, Corp." have also been found under the HKEY_CLASSES_ROOT or HKEY_LOCAL_USERS.
