Has anyone successfully installed Unity Pro v.4.1 on Windows Server 2003R2? Thanks!

 

We had the same problem, and at last we discovered that in the copy of the software there is an Install.bat file to make a "silent" installation. You can edit this file to correct the names of the drives and any other parameter (serial number, part number, etc), and then make it run. Surprisingly, it is much faster than the "setup installation", and surprisingly, it works fine.
