Re: [WiX-users] Prevent old InstallShield version from installing over WiX

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? -Original Message- From: Mike Schuett [mailto:michael.schu...@

The design of the 'old' install would have to be changed to check for the existence of the the new install, which is probably not feasible. I am not aware of anything that can be done in this situation. It is part of the price that is paid in transitioning from one design to a different design.
