I've installed 2011 Sp2 using the installation manager onto our new server (2008 R2)  to install Solidworks to both x86 XP clients and x64 Windows 7 clients.

When you run the installer (this is for our network licensing version) it correctly selects the x86 or x64 installer and begins. The 32 bit clients all work fine.

Not one of the x64 clients has installed successfully using the image created by the IM, they always fail at around 30% with internal error 1903 - and I've given up trying to diagnose that problem.

If I manually run the setup.exe in the Solidworks\x64 folder then it at least runs through the installation although it brings up an error near the end:

"Product: SolidWorks 2011 x64 Edition SP02 -- Error 1904.Module C:\Windows\SysWOW64\FM20.DLL failed to register. HRESULT -2147319780. Contact your support personnel."

If I chose to ignore this error Solidworks 2011 is installed, warns it may be incomplete!

I can't install the 32bit version on the x64 clients as the installer tells me that the version is incompatible which I suppose is technically correct although I'd settle for a working 32bit installation on the 64 bit machines!

Is there any way I can get this software to install the 64 bit version! It should not be this difficult to get installed.
