Hello,
I get "The application cannot be installed due to a certificate problem. The certificate does not match the installed application certificate, does not support application upgrades, or is invalid. Please contact the application author." error when I try to install Adobe XI.
How can I fix this? My windows 7 computer has Illustrator C6, InDesign C6, Media Encoder C6, Extension Manager CS6, ExtendScript Toolkit CS6, Creative Cloud, Content Viewer, and Bridge CS6 Adobe products on it, if this info helps.
