"Windows cannot access the specified device, path, or file" error when you try to install, update or start a program or file

If you are getting this error, most of the time I find this to be the fix:

Check to see if the file has been blocked by Windows

In some cases the file may be blocked by Windows. Check the properties of the file, there may be a note saying This file came from another computer and might be blocked to help protect this computer To check for and unblock the file, follow these steps:

1. Right-click the blocked file and then click Properties.
2. In the General tab, click Unblock if the option is available. 
3. Attempt to open the file or program.
