I'm running Windows 7 64Bit with SolidWorks 2009 and Beta2 2010 EPDM. All is good, performance is great, no problems at all.
It's a local install with the Database, Archive server and EPDM editor all on the C: drive.
I've been told EPDM running in Windows 7 won't officially be supported until at least 2010 SP1.
I'm running Windows 7 with SW 2009 SP 4.1 and EPDM 2009 SP3. The only issue I have had is that EPDM asks me to login to each of my vaults when viewing the root drive that contains the vaults in Explorer. Annoying, but bearable.
Many thanks to everyone who took the time to reply to my post. The information provided will be very useful
