I think you should be able to do this with the Upgrade element: <Upgrade Id="other apps upgrade code"> <UpgradeVersion Minimum="0.0.0" Maximum="max version" IncludeMinimum="no" OnlyDetect="yes" Property="OTHERAPPDETECTED" /> </Upgrade>
You can then use the OTHERAPPDETECTED property in conditions to block the uninstall.

In other words, given MSI's A and B, is there a way to express dependency between A and B so that A cannot be uninstalled if B is installed ? Have been reading and searching extensively to find solutions to this but haven't been able to figure a way out. Any help appreciated.
