Windows 7: Deleting a registry key that won't be deleted

I'm thinking the service pack needs to have a valid key so it knows were to apply the updates. As a service pack, it may not have all the .dll files necessary to run the ThumbsPlus program(s). This necessitates a previous installation and insures the service pack is not spread around and used to install copies. In other words, it must be applied to an existing installation.

You might well be right. Theoretically that SHOULDN'T be the case, as the "service pack" is the only download available, and the download page says "(Trial and Registered Full Install)" - bizarre, but I suppose that's so existing users know it's an update on version whatever. Anyway, have emailed Cerious support to ask if they can send a "correct" key in case that will help. I tried everything using MS knowledgebase, regnulldel etc. but that sucker isn't going anywhere.

I'm surprised nothing has been mentioned yet about registry key ownership and access permissions, which works very similar to NTFS file ownership/permissions.

Are you able to rightclick the offending key, select Permissions and then give yourself full access to it?

I couldn't follow the MS information referred to in that thread.

MS did a wonderfully horrible job on registry and file permissions. They should've just copied Unix/Linux.
FWIW, I've always been able to delete a reg entry .... with enough persistence.

You might try this for registry permissions (psexec is from Sysinternals):
Code:
$ Start "" psexec.exe -i -d -s c:\windows\regedit.exe
Note: it doesn't always work!

You also might try this (subinacl is from Sysinternals), maybe omitting the subdirectories part:

Code:
REM reset.cmd: Run this to change registry permissions.

subinacl /subkeyreg HKEY_LOCAL_MACHINE /setowner=Administrators 
subinacl /subkeyreg HKEY_CURRENT_USER /setowner=Administrators 
subinacl /subkeyreg HKEY_CLASSES_ROOT /setowner=Administrators 
subinacl /subdirectories %SystemDrive% /setowner=Administrators 

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=system=f
Are you able to rightclick the offending key, select Permissions and then give yourself full access to it?

Heh - I assumed he was trying that; start at the bottom at work up with the permissions...unless you can understand their gibberish about inheriting permissions - I sure can't.

I did mention permissions in the starter of the thread ... Yes, I have set full permissions on the key as far as I can, but I am not able to alter the permissions or perform any of the other right click options on the subkey which is my problem. (I can reset the permissions but it won't allow me to apply the changes.) I ran the reset commands (for which thanks, flemur) but no joy there either. (And he's a she, BTW! A very OLD she.)

MS knowledge base mentions that you can't delete keys with null characters, so I thought maybe that was it and downloaded the sysinternals utility that cleans THOSE out (regdelnull) but nada there either.

I officially surrender. I am not knowledgeable enough about this stuff to go much beyond what I've already done and what's been suggested. Thanks everyone.
