Do not Remove RegistryKeys on an upgrade

[Aaswin1996]

Current installer whenever upgrades it uninstalls the component and then installs it again .While uninstalling it also removes the registry keys . Is there some sort of a workaround using which I can ensure that during upgrades none of my registry keys are removed .

morning, according to stackoverflow, regkey element has property set it as "Permanent". BUT Attention on Permanent. This set regkey as System , cant be remove from installer .

Regkey("<your Defitiion>").SetPermanent(true);

something like that.
Works with Wixtoolset 3.X, for 4.X and better , dont know.

To me more accurate:

new RegValue("Count", 777).SetComponentPermanent(true),
