Hi everyone,

I have just come over the question if it is possible to share an MSI
that has been created with Wix and is being installed as a shared
component by multiple setup programs (being both Wix/Burn & 3rd party
Installers like NSIS...

I'm specifically interested in the un-install process.  Will the
Microsoft installer automatically do the reference-counting necessary
to make sure that one application's un-install process does not
remove components pre-maturely?

I know this works just fine if I install the shared MSI from multiple
Wix/Burn based installers, but will this still work if there are other
installers involved?

Best regards,
