Thinfinity VirtualUI Server License

As you well know, Thinfinity VirtualUI licensing’s model is built around concurrent users, the Server license is intended for production environments and you need as many licenses as concurrent users will access your application simultaneously.

Once you have your Server licenses, you can register them in the Thinfinity VirtualUI Server Manager under the “Licenses” tab.

You can find the .exe file to the VirtualUI Server Manager in “C:\Program Files\Thinfinity\VirtualU\bin64I”

Running windows desktop applications in the web browser

Click on the “Licenses” tab and then “Manage”.

2) In this window hit ‘add’ and select ‘Activate a Serial Number online’.
