These are the steps to provide admin privileges to the SKSE64:

  1. Locate the SKSE63 application in the SKSE folder directory and right-click on it.
  2. From the context menu for this executable, select Properties.
  3. Go into the Compatibility tab and click on the Run this program as an administrator checkbox, under the Settings section.
