The standard way to persist that ("the main application directory") is
to use a type 51 custom action and set the ARPINSTALLLOCATION property,
then it will get persisted in the MSI way (meaning that
MsiGetProductInfo with INSTALLPROPERTY_INSTALLLOCATION and other
standard APIs can get it).

Hello,

properties from a previous installation which i update with an major
upgrade using standard WIX functions?
Thanks
