Make a back up of the registry first
Look for the registry entries that are listed below. To resolve this issue, check the registry for the following keys and values. Re-create any missing keys or values. Note that these keys use the system drive letter.
You may have to adjust these entries to match the configuration of your computer.
[HKEY_CLASSES_ROOT\CLSID\{00000535-0000-0010-8000-00AA006D2EA4}]

If the Add/Remove Programs tool still does not function properly, shows no content, or if you want to try to fix this issue without upgrading to later versions of Internet Explorer, check the following registry keys to make sure that they contain entries:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\App Management\ARPCache
Note If the previous registry keys are blank, the Add/Remove Programs tool may also be blank.
Use the command line REGSVR32 [path\filename] to register each of the following files:
%systemroot%\System32\Appwiz.cpl
%systemroot%\System32\Mshtml.dll
%systemroot%\System32\Jscript.dll
%systemroot%\System32\Msi.dll
Program Files\Common Files\System\Ole DB\Oledb32.dll

%systemroot%\System32\Msdart32.dll [not registerable]
%systemroot%\System32\Mshtmled.dll
%systemroot%\System32\Mswstr10.dll [not registerable]
If the Add/Remove Programs tool displays incomplete information or is blank, verify the file dates and register, where possible, the following files:
%systemroot%\System32\Gdi32.dll [not registerable]
%systemroot%\System32\User32.dll [not registerable]
%systemroot%\System32\Msvcrt.dll [not registerable]

If the Add/Remove Programs tool can draw the dialog user interface, but does not display any installed program contents, check the registry for the presence of the following key:
HKEY_CLASSES_ROOT\CLSID\{352EC2B7-8B9A-11D1-B8AE-006008059382}\InProcServer32
If this registry key is missing, copy the following text to a text file, save the file with a .reg extension, and then double-click the file on the affected computer to return the proper entries.
For Windows Registry Editor Version 5.00:
[HKEY_CLASSES_ROOT\CLSID\{352EC2B7-8B9A-11D1-B8AE-006008059382}\InProcServer32]
