I too ran the corrected reg edit and when I tried to the right button it didn't work. I then rebooted my computer and it again failed.
I opened Reg Editor and looked for HKCU\Software.
That item did not appear at all.
This is the header of my Reg Editor
The HKCU isn't listed.
The {86ca1... did show up under HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}\InProcServer32
When I attempt to add the /ve /d /f to the InProcServer32, I get an error message
So, where do we go from here?
