Then follow these steps to run Regsvr32:
Step 1:
========
1. Click the Start button, then in the "Start Search" box, type CMD but DO NOT press Enter yet.
2. In the list above, under "Programs" right-click on CMD that appears above and choose "Run as Administrator" and click "Continue".
3. In the open window, type the following command and press Enter:
Regsvr32 msscript.ocx
Step 2:
=======
1 Run regedit.exe, locate the registry Key[HKEY_CLASSES_ROOT\Typelib\{0E59F1D2-1FBE-11D0-8FF2-00A0D10038BC}\1.0\0\Win32]
2 On the right pane, right click on the Default string value and select Permissions.
3 Give Administrators Full Control, assuming you are logged in as an Administrator.
