[melbourne-pug] Windows registry PermissionError

I'm trying to copy a value from HKLM to HKCU for application rollout via 
bulk installation by an administrator but individual Windows user 
authentication. The installer can write to HKLM but the user needs to 
see the value in HKCU

Any hints appreciated.

Thanks

Mike
