Hello, can please someone help me solve this problem.
I'm doing a major upgrade for every new release and this works fine. Current release version of setup.exe is 1.16. But... I tried to install 1.14 over 1.16 just to check what would happen and i got two applications in add/remove programs applet. I have uninstalled 1.16 from ARP and started 1.14 but 1.16 version got started... So my question is: How to prevent an earlier version of application to GET INSTALLED where a newer version ALREADY EXISTS?
Regards, Dejan

I have an extra line in my upgrade table that detects newer versions, then I throw an error if it is present.
The entries you need are:
Upgrade code: <Upgrade GUID>
Version min: <Current Version>
Version max: Blank
Attributes: 2
ActionProperty: NEWERVERSIONS
I then have a custom action in both sequences, if the property NEWERVERSIONS is set, it displays an error asking for the removal of the existing version.
