There is a kind of built-in way, and that's to set the ARPINSTALLLOCATION property (with a type 51 set property CA) after you know the folder location. The good part about this is that it exposes the location to the standard APIs such as using MsiGetProductInfo (....INSTALLPROPERTY_INSTALLLOCATION... ) and the equivalents in script etc. The bad part about it is that retrieving it requires code because the registry search to find it is awkward. --------------- Phil Wilson
