It was Working Fine before the update.I opened the game one time after the update and closed it.Next day When i was trying to Open it this Error came.

Reinstall looks like a good option at this point.

Then every time this error come i have to reinstall?

If I understand correctly, the game worked once after the update. This is just a stab in the dark (sorry), but did your antivirus/anti-malware tools get any updates in the meantime?

Edit: ...also, is Windows event viewer log showing any events at the corresponding times?

Try reinstalling.
