If you get error 1902 when you try to start the raysat satellite service, it’s probably because there is no entry for the service in the services file.

C:\Program Files\Autodesk\Softimage 2011\Application\bin>raysatsi2011_3_8_1_31server.exe /install
RaySatsi2011_3_8_1_31 Server installed.
Starting RaySatsi2011_3_8_1_31 Server.
raysatsi2011_3_8_1_31server error: (1092) RaySatsi2011_3_8_1_31 Server failed to start

Use a text editor to edit C:\Windows\system32\drivers\etc\services and add an entry that looks like this:

mi-raysatsi2011_3_8_1_31 7004/tcp	#

I’ve used port 7004 in this example, but you’ll have to check that no other service is using that port.
