It depends how many prior versions you've got as to how cumbersome this is, but if you had 1.0, 2.0 and 3.0 then you can simply use upgrade elements to detect each of them with onlydetect=yes, and if the corresponding property is set show a message.
It's not obvious what version you really want - the product version of your installed product is the same as the version of an installed assembly only if you deliberately made it the same.

Howdy gang, In my installer I need to notify user if the previous version of product is installed and show the version number. I was hoping that I can find the already installed version number in PATCHFOUND property I use in UpgradeVersion stuff: <Upgrade Id="5F966E51-1220-47e4-9825-9909C91033D4"> <UpgradeVersion OnlyDetect="no" Property="PATCHFOUND" Minimum="0.0.0.0"> </UpgradeVersion> </Upgrade> However, the value of property is just some GUID. I know the way I can accomplish this task - call the custom action that executes the external program that loads the installed assembly and returns it's version number, likely the assembly version is the same as the installed product version. However this way is not straightforward . I am sure that Wix has the way to detect the already installed version number, just can't find it. Can anyone help me? -- View this message in context: http://n2.nabble.com/Detect-the-version-of-already-installed-product.-tp1344094p1344094.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users
