Thanks for getting back to us with additional details, @chrtucke.
Can you please tell us what specific error message you encountered?
While we wait for your response, I would like to guide you through some general troubleshooting steps to fix issues when your QuickBooks Desktop (QBDT) company file won't open.
- Update QBDT to the latest release.
- Ensure you want to open a company file (.QBW). You can't open other file types, like backups (QBB) and portable files (QBM) the same way.
- Confirm that your file isn't compressed or encrypted:
- Right-click the company file and choose Properties.
- Select Advanced.
- Clear the Compress and Encrypt checkboxes.
- Click OK.
- If you still can't open your company file, choose your company file in No Company Open.
- Press and hold ALT on your keyboard and then select Open. Keep holding the ALT key until the file opens. If QuickBooks prompts you to sign in, release ALT and enter your password. Press and hold ALT again and click OK.
- If your company opens successfully, turn off the Save the desktop when closing preference.
- Go to Edit and select Preferences.
- Choose Desktop View.
- Click Don't save the desktop and then OK.
- Close and open QuickBooks again, then pull up your company file.
If it opens successfully, then you're good to go. However, if you can't open your company file, refer to this article's Solution 3: Turn off hosting on your workstations section: Can't open your company file in QuickBooks Desktop.
Moreover, you can access QBDT remotely from a host or server computer. For more details, check out this article: Open a company file on a remote computer.
