Proper way to solve known problem ".NET exception occurred: System.IO.IOException: Access is denied"

[Ilmari Lauhakangas]

A new developer hit this known problem 
https://wiki.documentfoundation.org/Development/BuildingOnWindows#.NET_exception_occurred:_System.IO.IOException:_Access_is_denied

Permissions for the C:\ProgramData\Microsoft\Crypto were changed as 
evidenced by this screenshot: https://pasteboard.co/cjAj4V1PoRFw.png

Checking in PowerShell with

cd C:\ProgramData\Microsoft\Crypto
Get-Acl | fl

this is the output:

Path   : 
Microsoft.PowerShell.Core\FileSystem::C:\ProgramData\Microsoft\Crypto
Owner  : NT AUTHORITY\SYSTEM
Group  : NT AUTHORITY\SYSTEM
Access : BUILTIN\Users Allow  Modify, Synchronize
          NT AUTHORITY\SYSTEM Allow  FullControl
          BUILTIN\Administrators Allow  FullControl
          BUILTIN\Users Allow  ReadAndExecute, Synchronize
          Everyone Allow  ReadAndExecute, Synchronize

Yet the error kept appearing. Any ideas?
