I managed to install my ArchiCAD 10 in the "XPM" environment on my Win7 Pro 64bit PC. The trouble is, that when I start ArchiCAD, I get the message that
"It's not possible to run ArchiCAD in a terminal service client"
As from our official swiss reseller's technical support, I have been told that it IS possible to install it in XPM, even though it is NOT supported officially by Graphisoft.
At the same time, I read on this site
I had the same problem trying to install 10 on my new desktop. I have it dual boot XP Pro and 7 Pro 64 bit. Xp works fine, but 7 would not finish the install, it would go all the way up to the point which folder it was going to be installed then it would fail. Then I read about the Java so I installed 6-21 and then I was able to install Archicad 10. Everything seems to work fine except 3D Open GL mode. The only time there is an image is when panning or orbit. I have the latest 7 64 bit video driver (18.104.22.16815)
