I got the solution from internet and resolved this issue. So, I have decided to share with you, just you have to reinstall Microsoft Visual C++ 2005 Redistributable Package (x86).
· Microsoft Visual C++ 2005 Redistributable Package (x86)
· Microsoft Visual C++ 2005 SP1 Redistributable Package (x86)
Note: If you have alternative solution, please comments below to share with us.
