but when launching splash screen appears then quickly disapears and nothing hapends afterwards
it apears with trueview2009, trueview2010, designreview2009, designreview2010, mechanical 2008, acad2008
there was acad2004 insalled but i needed to open drawings in 2009 format
so i installed trueview2009 it didn't run
so i installed trueview2010 it didn't run also then i uninstalled the acad2004 but it didn't help
them i installed the designreview and then the mechanical2008 and none of them opens
WinXP or Vista?
Does the PC system meet the SSE2 requirement?
.NET Framework 3.5 sp1 installed?
is DEP in Windows holding off the launching of the apps?
Are you logged in as full administrator?
Does R2004 still work?
DTV2010 have a patch for a similar symptom, did you try that?
The fact that 5apps do not run is an indication of a Windows or system choke
