This also ensures a clear separation in the system registry. SelfReg is not recommended by Microsoft and will be handled by the MSI package to allow proper Repair and Uninstall. However, we keep it for backward compatibility with the NSIS installer. For details see: https://stackoverflow.com/questions/364187/how-do-you-register-a-win32-com-dll-file-in-wix-3#364210 https://docs.microsoft.com/en-us/windows/win32/msi/selfreg-table#remarks Another fix by this commit: The "Version" registry value in the NCOverlays self reg should be a key and not a value. Details: https://wixtoolset.org/documentation/manual/v3/xsd/wix/class.html Example: [HKCR\CLSID\{01234567-89AB-CDEF-0123-456789ABCDEF}\Version] @="1.0.0.0" Signed-off-by: Michael Schuster <michael@schuster.ms>
