When trying to install crystal reports 9 Developer, I get an error message stating u201CInstall cannot proceed because Crystal Reports 9 9.2.2.5706 has been detectedu201D. I have Crystal reports 10, XI R2 Service pack 3, and 2008 installed. However, crystal reports 9 should not be detected on my development machine. Can crystal reports 9 be installed with the other versions on the same machine?
