    Hi Nirmal,

    I had tried to uninstall the msiexec as stated above. But even the very first step did not execute.

    As I type Msiexec /unreg in cmd in admin mode, it pops up an error dialog box titled unsupported 16-bit application. Attached is the image.

    This is what I get on cmd as I click on ok of dialog box:

    Microsoft Windows [Version 6.1.7601]

    Copyright (c) 2009 Microsoft Corporation.  All rights reserved.

    C:\Windows\system32>msiexec/unreg

    This version of C:\Windows\system32\msiexec.exe is not compatible with the versi

    on of Windows you're running. Check your computer's system information to see wh

    ether you need a x86 (32-bit) or x64 (64-bit) version of the program, and then c

    ontact the software publisher.

    C:\Windows\system32>
