Try that suggestion:

Apart from one small change, instead of Comctl32.Dll, use SHLWAPI.DLL instead in the instructions.

That may solve your problem then again, this problem could be caused by faulty hardware, a damaged XP CD, or something else totally different.

Take it a step at a time, try as many suggestions as you can until you get it solved.
