How to Fix: Office Installer Won’t Open

Getting an error like “Access is denied” when opening the Office installer? Here’s how to fix it.

Updated yesterday

If you’re seeing one of the following messages when trying to open the Office installation file:

  • Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.

  • Unable to execute file in the temporary directory. Setup aborted.

  • Error 5: Access is denied.

This is almost always caused by a third-party antivirus blocking the file from running — even if the file is safe.


Step 1: Temporarily disable your antivirus software

In most cases, the issue is resolved by:

  • Turning off your third-party antivirus software completely

  • Adding an exception for the installer file inside your antivirus settings

Once the antivirus is disabled or the file is allowed, try opening the Office installer again.

This applies even if you don’t see a direct warning from your antivirus — the block may happen silently in the background.

If disabling antivirus doesn’t help, try the alternative solution shown in the video below:
