ERROR 3371

Hello there, @ENJOYHOME.

Thanks for taking the time to reached out to us. Let me help you get this sorted out to keep your QuickBooks running and so you can get back to your business.

You're on the right track processing the troubleshooting steps to isolate this error. Now, since the program data file you're looking for is actually a hidden folder, what you need to do is unhide the folder. 

Let me walk you through the steps:

1. Right-click the Start button, then select Control Panel.
2. Go to Appearance and Personalization, then select File Explorer Options.
3. Click the View tab.
4. Scroll down a bit and change the Hidden files and folders setting to Show hidden files, folders, and drives. Optionally, you may wish to uncheck the Hide protected operating system files box as well. 
5. Once done, click OK.

If you need further assistance with the steps, I recommend calling our QuickBooks Point of Sale Team. They have the tools to pull up your account and do a remote session. 

That should do it! Please that you're always welcome to post if you have any other questions about QuickBoosk POS. Wishing you and your business continued success.
