Core 2 Duo machines E6600 - frankly minimum required due to revit 9.1 and older running like a dog
2Gig ram - technically its enough but looking at going to 4Gigs to avoid the problem below ( really doubt the 2G is used up at all, normally off the previous versions it would equate to around 350M? to 600M? used)
195Meg File size
Xp Pro
It was due to an upgrade from 9.1 to 2008 running out of memory.
Reopened file again and this was fine.
Anyone else encountered memory errors in 2008?
