The Upgrade stuff is good at detecting specific versions of installed products using UpgradeCode. That can be used to set a property if the product is found. There's a potential sequencing issue because FindRelatedProducts is what detects previous versions, so I'd use a type 19 custom action sequenced after FindRelatedProducts conditioned on the property in the Upgrade search (that's set to only detect).
If there's a specific component guid unique to that previous version, then (impersonating Rob) I'd do a ComponentSearch for that component guid, then that property can be used in a launch condition.

Subject: Re: [WiX-users] ALLUSERS property and upgrades That's unfortunate, thanks for confirming that for me though. Any idea how to craft a Condition element that's based on a previous installation's Product's Version setting?
