Received the following error after running Add/Remove
Programs in Control Panel. Now there are no programs
listed in Add/Remove Programs box. How easy is it to
repair the registry per instructions posted on Microsoft
website? Need input!!!

Error: An unexpected error occurred. Class not
registered. res://appwiz.cpl/listbox.htc Line: 225
 
From the "Run" box try;
regsvr32 %windir%\system32\appwiz.cpl

regsvr32 %windir%\system32\webvw.dll
to rebuild several *.htt files

If unsuccessful try
sfc /purgecache
sfc /scannow

Or try the regedits described in;

If the problem persists, you'll likely need to perform an in-place upgrade.
