You'll need something to set the REMOVE property.

Alternatively, you could possibly make some components permanent but that's
going to be messy because there's no way to ever remove the drivers cleanly.
For an in-house application, that may be acceptable.

yes. the situation is that I have to make installer of program that supports
compatibility with old versions (not MSI technology) of other product. this
old version have some its own shared counters in registry. so i must do so
that if MSI installer found that counter in registry it will not uninstall
some drivers while uninstalling (cause this drivers are using by old program
too).
