If you ever run an installer and get the following message “Windows cannot access the specified device, path, or file. You may not have the appropiate permission to access the item” try the below. Note: I am assuming that you already have rights…
1. Copy the file to your local machine
2. Right click on the file and go to Properties.
3. Down at the bottom of the General tab you might see a Security option that says “This file came from another computer and might be blocked to help protect this computer.”
4. Click Unblock.
