After choosing Properties, pick Compatibility. “Run this software as an administrator?” should be checked. Click Ok after choosing Apply.

Give appropriate permissions

The issue is often spawned when the app cannot change your system because of denial of permissions. The permission settings of your operating system prevented you from using the Blizzard desktop program. To continue, you must let the Blizzard desktop software make modifications.

Enter your administrator password in the notice window, if needed, when the Blizzard desktop software wants to make a change, and then click OK.

  • Press Win+R on your desktop.
  • In the run command box that opens, type %tmp% and hit Enter.
  • The temporary files on the PC will all show up; choose them all.
  • At this point, press shift+del and enter. All temporary files will, after that, be deleted from your computer.
