MsiGetProductInfo for the location only if your setup has a type 51 custom action that sets ARPINSTALLLOCATION to the actual installation folder. Not all of them do.

It seems that this code works just fine: 

wchar_t installDirPrev[4096];
DWORD isBuffer = 4096;
MsiGetProductInfo(productCode, INSTALLPROPERTY_INSTALLLOCATION, installDirPrev, &isBuffer);
