View Full Version : XP SP3 Install Fails to Detect Existing Instances

Our product installer is not detecting existing instances (and therefore not offering the client the chance to upgrade) on a machine running Win XP SP3. The same installer running on Win XP SP2 does properly recognize the previous installations.

Anyone got any ideas or KB articles you can point me at? Are there system components replaces in the SP3 upgrade that we might have to do something about?

This isn't fatal but certainly is annoying.
