[wix-users] Question about MSP patches

[Joel Budreau]

Hi all,

I’ve got an MSI that I’m going to generate .msp patches for as hotfixes are necessary. The patches will be cumulative (like the following)…

Release 1.0.0 MSI
Release Hotpatch 1 (includes bug fix A)
Release Hotpatch 2 (includes bug fix A and B)

If a customer installs the MSI + hp1 + hp2 and then accidentally tries to re-install hp1 it seems like msiexec will consider hp1 and hp2, notice that hp1 is obsolete, and simply re-install the MSI + hp2 patch. I’d like it to actually exit with some error saying that hp1 is obsolete and not perform any installation. How would this be possible?

Thanks,
Joel
