Hey DeOlijus-

The RC1015 error shown in the error message likely indicates that you are missing the Windows SDK on your computer. You can find more information on the RC1015 error along with a link to download the Windows 7 SDK on the wiki page linked below. Keep in mind if you are using Windows 8 or Windows 10 you will need to get the appropriate SDK.
