Depends on what the old install looked like, as far as it's upgrade table. Did the old install allow for downgrades? If not, did you use the same upgrade code in your WiX install as you had in your install shield installer?

Installation of the new product version (WiX based) over older versions (IS MSI based) works fine. The problem I'm having is the old IS installs do not recognize the newer WiX installations and I end up with two installations. Any suggestions would be appreciated.
