we have a setup developed in installshield vr 6.3. it is a self extractable single setup. it work fine in most on most of the Windows version but on Windows server 2003 64bit in Execution mode when doing RD it return user windows directory against WINDIR i.e. c:\documents & settings\fcuser\windows instead of C:\Windows. According to http://support.microsoft.com/?kbid=186499 it should work fine when i change the compatibility bit of Setup but it didn't. i tried changing compatibility bit of these key too (INSTRUN, SETUP and SETUP1 ) but it didn't work either. but when i when i run the setup within the self extractable by extracting it work fine.
