Can't delete registry key

A program left a registry key that I can not delete
(first of all, this does NOT represent a security
issue - I have full control permissions on the key).

Regedit.
If I attempt to actually access the key, I get:

"Cannot open data: Error while opening key."

If I attempt to delete the parent key, I get:

"Cannot delete (keyname). Error while deleting key."

Rededt32.
The key appears "greyed out" (a sort of silver color).

If I attempt to delete the key (or the parent), I get:

"Registry Editor could not delete the key currently
selected. The key, or one of its subkeys is not
accessible."

How do I delete this key?

Have you tried logging in 'Safe' Mode and try to delete the key? What Hive is it in and what key specifically?

use regedt32, and then from the menus change the permissions to give yourself full control of the registry key - after this you should be able to delete it.

JammyPak is correct.  This is usually a system protected key, like hardware.  What are you taking out?

I have not tried logging in in safe mode yet. I will try
when I have an opportunity to reboot the machine.

The problem key is:
HKEY_CURRENT_USER\Software\ASVzzz\TheFly\Data

This does not seem hardware-related.

Some people did not read what I said carefully. I will
repeat. THIS IS NOT (by itself) A PERMISSIONS PROBLEM.

I have full control (with propogation) up to
HKEY_CURRENT_USER. When I select Security/Permissions on
the problem key (Data) with regedt32, I get:

"Unable to display security information."

I HAVE tried to "reset permissions on all child objects..."
on the parent key (that gets a message "Registry Ediror
could not set security in the key currently selected or
some of its subkeys."

If necessary, I want to back up the entire registry
(at least this hive), which presumably will not
include the affected key, and recreate it from the
backup.

Everyone who has posted here has probably long forgotten
about this problem, but I did finally get it solved.

First of all, I tried every advanced registry editing tool
I could find, even logging in as administrator to keep the
hive unloaded. I got absolutely nowhere.

Finally, I came across this "Offline NT Password & Registry
Editor" (actually a Linux boot disk with a registry editing
tool) at:

http://home.eunet.no/~pnordahl/ntpasswd/

While not exactly trivial, the whole process did seem quite
straightforward, and I had the key deleted in just a couple
of minutes, and no problems after rebooting.

Thank you for your help.

I have attempted to use this method of repair utilizing a Winternals CD (Linux boot CD) to no avail.  When I drill down to the registry location that is corrupted and attempt to reset the registry I receive the following error. FILE NOT FOUND.

In Windows I attempted to run regedt32 utilizing the local system account by running the following command
cmd /k at 13:54 /interactive cmd.exe  (time set for 1 minute later that current time)

when command prompt appears type regedt32 in command window

The registry locations are
HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\MLSAS000
HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\MLSAS001
HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\MLSAS002
HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\MLSAS003
HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\MLSAS004
HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\SAC
HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\SAI
HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\SCM:{3D14228D-FBE1-11D0-995D-00C04FD919C1}
HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\TS:InternetConnectorPswd
HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\XATM:c415e421-f331-4c89-8d70-1d0289db1b01

THis seems to be an issue with missing from the system that may be required to access teh registry settings.
