Start by right-clicking on the last sub-key which in this case is InProcServer32 and click on Permissions the Advanced then change Ownership to yourself.
Assuming you're on Windows 10 click on Change -> Advanced again -> Find Now -> Administrators.
Then tick the "Replace owner on subcontainers and objects" and also "Replace all child object permission entries..."
Click OK
Then select "Administrators" in the Permissions window you first opened and tick "Full Control" then hit OK
Do that to the InProcServer32 folder and the {42aedc87-2188-41fd-b9a3-0c966feabec1} in both HKEY paths
As for the reg file itself that i uploaded Right Click -> Properties -> Security tab ->follow the general steps i wrote above
