A Little Help With "uxheme.dll" Issues Please?

So, I've been using custom themes in my Win7 for ages, and it's never given me any trouble... Until today.

I tried to switch to a new theme today, and it took me back to the windows basic theme. I thought at first it was a problem with either the theme itself, or with the folder I put it in, so I tried to switch back to my old Slate theme (awesome theme is anybody is interested: Slate Windows 7 Aero by ~Eoin on deviantART), but even that won't load now.

I tried reinstalling my "UxStyle Core" service again, didn't give me any errors, but even after restarting it wouldn't apply any third party themes. My standard Aero themes still work properly, only third-party don't.

I found a post here that I thought might help:

Rafael said:

UxStyle will install an "Unsigned Themes" service. If you don't see this, I suggest you attempt re-installation. You did download it, right?

UxStyle requires that all system files be intact and in original format before it'll work correctly. I also suggest, after UxStyle installation, that you run the following commands in an elevated command prompt (this is fixed in our next build):

sc config uxpatch group= "File System"
sc config UnsignedThemes group= UIGroup


NOTE: The spaces are intended, do not modify the commands.

But I can't find any services with those names in my services list, and I can't seem to find any other way to install them... Also when I try run those two commands in an elevated command prompt, I get the same error with each:

Code:

C:\Windows\system32>sc config UnsignedThemes group= UIGroup
[SC] OpenService FAILED 1060:

The specified service does not exist as an installed service.


C:\Windows\system32>sc config uxpatch group= "File System"
[SC] OpenService FAILED 1060:

The specified service does not exist as an installed service.

Just to confirm I hadn't accidentally tried to use two differnt patches at once, I checked my uxtheme.dll file with "sfc /scanfile", and it's fine:

Code:

C:\Windows\system32>sfc /scanfile="c:\windows\system32\uctheme.dll"


Windows Resource Protection could not perform the requested operation.

Because the UxStyle Core is a '.msi' file and not '.exe', I can't find a way to run as administrator, but that wasn't ever a problem before. Can anybody give me some suggestions on what to try next?
