We have purchased seven of these 30 packs of Rhino, the seven packs of 30 included 4 packs  with upgrades to version 5 and 3 pack included version 5.

I can input four of the serial numbers, when I input number fifth serial number – I can activated software, and  Zoo server will error out stating it to cannot communicate with service.  Does not matter – what order in how I input the serial numbers – when I reach total of 120 individual licenses, and I want to add another 30 – it will activated and  Zoo server will error out stating it to cannot communicate with service.

I had installed version zoo50_20120927_2215.msi, and  zoo50_20121128_1310.msi, and  zoo50_20121217_0240.msi.  All of  these version do the same thing.

When I reach total of 120 total individual licenses in zoo, and I add another 30, and Zoo server errors out that it cannot communicate with service. No others errors is recorded in the event viewer.

Zoo 5 server is installed Windows 2008 R2 - no IIS installed meaning nothing is on port 80, .Net 4 is installed.

Only other servies is Flex license services for Autodesk.

We had Zoo 4 installed on anther server, it was disabled and removed. We need to roll out Rhino 5 to 500 student workstations with Windows 7 x64 in early January 2013.
