Failed to execute admin command

How do I fix this issue when I try to install.

Your anti-virus software is most likely blocking programs from running from the temp directory.

Please try adding an exception in your anti-virus software for your Everything.1.4.1.895.x64-Setup.exe and try again.

-or-

Please try the portable version of Everything:

• Download the portable version of Everything.
• Extract Everything.exe to C:\Program Files\Everything
• Run Everything.exe
• If prompted with Access Denied, choose Install Everything Service and click OK.
• In Everything, from the Tools menu, click Options.
  Click the General tab on the left.
• Check Store settings and data in %APPDATA%\Everything.
• Check Everything Service.
• Uncheck Run as administrator.
• Check Show Search Everything folder context menu item.
• Check Start menu shortcuts.
• Check Desktop shortcut.
• Check EFU file association.
• Click OK.

@void: Just want to say that it is pretty impressive how you got from this cryptic message:

to this diagnosis:

Your anti-virus software is most likely blocking programs from running from the temp directory.

Amazing!

Now I really hope @mac1 reports back ...
