Unity.exe - System error

Hello! If im trying to open unity im getting this error:

Unity.exe - system error the program cant start because MSVCP120.DLL is missing from your computer. Try reinstalling the program to fix this problem.

Yesterday everything worked fine and today im getting this error. I reinstalled the program but I still have the same problem.

Thanks!

I know this is old, but it may be helpful to others with a workable answer.
I’ve now spent a day or two running around the web looking for answers and reinstalling all kinds of things. Installing, uninstalling, repairing this DLL, but to no avail. Finally, I did a search for the Redistributables myself and found a link that had a newer package (by the version number) and it worked without reinstalling Unity again.

This lib worked for me. I hope it works for you, too.
