I'm trying to install CS3 Server on Vista, but get a setup error also on Windows 2000 Server it is not working.
Finally I'm trying to install it on XP it is running the installation program but at the installation options I cannot continue.
I had the same problem too but found out what caused it.
InDesign Server can only run on the following:
1) Mac OSX Server 10.4.x or higher
2) MS Windows Server 2003, with the most current Service Packs installed.
3) Microsoft .Net Framework Version 2.0 (not 1 or 3 because it won't install)
