Hi,
I uninstalled my TS2010 with the uninstall tool on this site.
Then went to install (online version) TS2011 and during the screen after terms conditions BSOD.
Then tried the install 2x more and same thing.
Tried install (offline version) same thing again, but least this time don't need download 200mb again to retry!
Any help be great, brand new system, was tested fully at system builds.
Only reason went to install TS2011 was that I couldn't get remote desktop to work even though setup 100% same way as my old XP system, Support told me to upgrade.... That was great help 
Joseph.
