I attempted to change the security through regedit and it won't allow me due
to insufficient permissions. I even tried via safe mode.

Hi
You can trace which registry key is causing the trouble using the
setupapi.log in the windows folder (this log file is updated during
a service pack installation).
Here is a previous post about this:

Subject: XP SP2 "Access Denied" & the Fix

As with SP2 RC2, I am having the same problem with the GA
release of SP2. "Access Denied" during installation.
This is error can be worked around by reading the
setupapi.log under the windows directory. I am
posting this to see if others are having the problem. For
some reason several registry keys related to windows media
player and a few others do not have any permissions set
for admin and system.
Specifically the following need to have permissions set to
full control for admin & system:
HKCR/vnd.ms.radio
IP6FwAPI.NetFirewallV6Manager
HKCR/WMPlater.OCX/EditFlags
HKCR/Software/Classes/UICTL* may vary
HKCR/Software/Classes/ADDC* may vary
you may have others so check the log for "Unable to delete
registry , Access Denied"
You may need to go thru the install a few times, as you
may fix one set, the next time you run it you may
encounter a new set. The best thing to do is check the
first 3 listed above and the set full control on
permission to HKCR/Software/Classes and its child objects
for Admin and System only.

The above might be a very laborious if there are several registry
keys that have a permission issue. In that case, it would be
better to reset the security settings back to the defaults for
all registry keys.
More here on how to do that:

If you only want to reset the registry permissions,
add this to the secedit command line:
