ACCESS_DENIED on update

[Boylan, Ross]

I refreshed (craft -i) my installations of craft and craft-blueprints-kde, executed
craft --set version=1.76.0 libs/boost
(it was version=rblocal, which produced errors that it was not an available version)
And then
Craft -I kdiff3
I previously installed kdiff3.  This ran for quite awhile, but failed with an access violation.  Any ideas?

This is odd since I'm running as admin in powershell and created the file in a very similar environment.  I executed
.\craft\craftenv.ps1
At the start, though I did not do Set-ExecutionPolicy -Scope CurrentUser RemoteSigned as I did during the initial install.

The file and the directory it is in show local machine administrators as the owner; regular users do not have permission to delete.  My regular user identity is not among the listed principals for the file or directory.
