With this solution, now I have more games to enjoy. I had given up and tired of getting 100% ERROR message after a progress of 100GB download. (at least for me) the installation works normally after pressing 'retry' button. Sometimes the game would not install at the first try, but in those cases In diskpart context, display the current SAN policy:ĭiskPart successfully changed the SAN policy for the current operating system.Īnd that is it! From now on there should be no permanent error when installing games with 'Administrator approval required for installation'. Run the command prompt as administrator and run the diskpart. Previous versions also supported Windows XP and Vista. I tried your workaround (it works!) and thanks to you managed to figure out a permanent solution to dreaded error 0x8007001f The latest version of Apple's Boot Camp solution, which lets you dual boot a Mac between Mac OS X and Windows, now only works with Windows 7.

And, just like with using Bootcamp or Parallels on MacOS, I want to mention that I still needed to buy a valid, unused Windows 10 license key to legally and properly activate Windows. Post a reply if that fixes your 0x8007001f issue. Apple still recommends Bootcamp as the best method for installing Windows 10 on a Mac.
