Could you go to the directory "C:\Windows\SysWOW64" and search for "msvcp120.dll" in there by using the search box at the top right of the window?
If the file is not found, try reinstalling the vcredist_x64 again, restart the PC and let me know how it goes. 🙂
Okay, go to Computer in the start menu and open it. Double click Local Disk, then the Windows folder, and then SysWOW64 folder. Windows may pop up with a warning about editing the files in these folders. Don't worry about that, just be very sure not to move or delete anything in these folders.
At the top right of the window itself will be a search bar, type in msvcp120.dll and wait a minute for it to search. If it states that there are no results, then vcredist_x64 did not install correctly.
Unfortunately not, try to reinstall the vcredist_x64, by right-clicking "vcredist_x64.exe" and "Run as administrator", restart the PC and try to search for the file again, let me know if the file is there afterwards. 🙂
Okay, open vcredist_x64.exe and click uninstall. Your PC may need to restart afterwards, once it has, install it as normal.
Edit: I apologise for all this. Computers can be quite a hassle. :P
Okay, install vcredist_x86 as well, and see if that makes a difference.
Edit: Also, just to be sure, are you downloading the files from here?
