Windows 7 Pro; Key under: hkcu\software\program\ . . . \Display

can't delete the key with regedit; permissions for the key shows no authority for any user class; can't change auth; key creates error on software install

I have admin privledges on this machine; rec'd a 1402 error msg while tring to install new software (there was a prior version of the same software on the machine that had been uninstalled);

are you running regedit as administrator..  I don't mean logged in as. I mean right click and select run as administrator.

Another possible workaround is to log into the physical admin account - then run a elevated command prompt from within the account, and then run regedit from that command prompt.  (It will still launch the normal regedit application, but this can help resolve some of the "run as" problems I've seen before.

You may also want to check into any possible services that are running connected to the reg key.

If you download NDR Commander then you can edit the reg from a system user (bootable support CD)

There are many other bootable CD's that can do the same task.

Or if you use regdt32 then you can change the security with the registry..

Try running regedit as SYSTEM using the runassys utility found on this website
http://blog.delphi-jedi.net/2008/05/08/runassys-10-preview/

it will run regedit with even more elevated permissions than administrator

none of the above were easy to implement, but collectively, they suggested the right search phrase and I solved it; fyi, see:
