Related to Feedback ID: 225101Adding as new feedback item since I can't execute my VS 2005 IDE (devenv.exe) after installation failed. The installation Rollback did not rollback to a usable state. Comment duplicated on 225101: I had 2.2 gig free prior to installing, and mine failed w/ 8 minutes remaining on XP Pro (us english) w/ VS2005 Team Edition Software Developer. The "Retry" option failed to have any effect during the install. Once I received the "free some disk space and click Retry. Or click Cancel to exit..." message (I believe the file was something like MFC80???.AMD64.pdb), I found a 400+ meg .iso file that I could permanently delete (shift-del), then clicked "Retry". Immediately afterwards I got another message telling me the install failed and then the freakin' thing backed all of the way back out. After it finished backing out of the install, I never received any sort of a confirmation message / failure notice that the install failed. And... now I can't open my VS IDE. I get a "devenv.exe - Application Error" message stating "The application failed to initialize properly (0xc0150004). Click on OK to terminate the application."
