try to Start Button\Run and type appwiz.cpl and click OK. the add-remove programs will appear on your screen( it the name of the program ). If it does not launch then appwiz is corrupted or missing from the windows\system32 directory an can be restored using system file checker.

a Other cause could be that the logged on user does not have permissions to install and uninstall programs, which can be set by tweaking the registry or by using policy editor.

If that all didnt work then, you may have some missing registry entries.

To fix the problem:

1. Open a CMD.EXE prompt.
   
2. Type regsvr32 mshtml.dll and press Enter and OK.
   
3. Type regsvr32 shdocvw.dll -i and press Enter and OK.
   
4. Type regsvr32 shell32.dll -i and press Enter and OK.
