Hi there, DennisT.
Welcome back to the QuickBooks Community. I appreciate you for sharing detailed information about what you've done to resolve the issue so you can get back on track. With this, I'll be providing troubleshooting steps to ensure you can back up your QuickBooks Desktop data file with Intuit Data Protect without any issues.
To start with, Intuit Data Protect needs access to your firewall. That said, I suggest checking your firewall to make sure important files are allowed and aren’t blocking Intuit Data Protect.
Here's how:
- Press the Windows key on your keyboard and type Firewall in the search field.
- Choose Allow an app through Windows Firewall. Then, Allow another app.
- Select Browse and go to Program Files(x86)\Common Files\Intuit\Data Protect.
- Click QBIDPservice.exe and Open.
- Select Network types and select the Private checkbox. Select Add.
- Repeat steps 4 and 5 for the files IBUenghost.exe and IntuitDataProtect.exe. If you get a message saying the files already exist, you’re all set.
Once done, ensure that Intuit websites are trusted sites in Internet Explorer. You can open this article to see further details and how to perform the process: Can't back up with Intuit Data Protect?. This also provides an additional solution to completely fix the issue.
Lastly, you may refer to this article to view different details on how you can resolve general problems when your company file won't open: What to do if you can't open your company file in QuickBooks Desktop.
Keep me posted if you have any other questions or concerns about managing your data. I'll make sure to get back to you as soon as I can. Always take care!
