CamtasiaStudio won’t run on Windows 7 Operating System

Hi,
I am using Windows 7 Operating System and getting System Error message that the program can’t start because WMVCore.DLL is missing. I have tried to reinstall the program to fix this program but could not solve this issue. Can I fix this error without having any problem? I really need your assistance.
Thanks for any help.

The program can’t start because WMVCore.DLL is missing from your computer. Try reinstalling the program to fix this problem.
