“Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.”
This message isn’t entirely accurate and frustrating when you forget what the simple resolution is. In many cases to resolve this, you simply need to unblock the file from the file’s properies window.
To do so:
1) Right-Click on file and Select Properties
2) Select the General Tab.
3) Click the Unblock button.
The first time I recieved this message I pulled out some of my hair after trying the file on multiple machines and different versions of Windows, checking security, etc. I was being smarter than I actually was which led to taking this simple problem to a major one. Anyway, if you are searching for this error and found this page, chances are that I have saved you some hair as well.
