Hi everbody, I just joined this forum today. I am looking for help with the following problem. When I try to install a certain prog from a cd I get the error message 2721 stating that I must uninstall another version of this prog. It then asks me if I want to uninstall now, and when I click yes, it just repeats this in a loop. I have looked in the registry and there is no other version of the prog installed. Any suggestions please ? G
