We run both 32-bit and 64-bit versions of SolidWorks 2010. This time round I tried the admin image route and have both 32 and 64 bit images on a 32-bit server. Didn't experience any issues with running 64-bit installs from a 32-bit server.
Hope that helps.
Did you set up both admin images from the 32-bit server, or did you setup the 64-bit image from a 64-bit machine?
This used to work for us. SInce SW2011 SP4.0 however, it no longer creates the 64 bit admin images and complains about the server only being 32 bit. I complain about it too, but cannot aford W2008 R2 server right now, so we have to use what we have.
I started another thread on this very issue under Adminstration / Installation
