How do i open a backup of a previous version of qb? I just installed qb pro 2020. I tried to open, to restore, nothing is actually bringing it into my qb. thanks!

Glad to have you here, @brooksnyder-yaho,

I can definitely help you find and open your company file back up.

The location of your back up depends on where the file is originally stored. This is given that there isn't any changes made to the back up path. You can open the Product Information page to trace the .QBW (working file) file path by pressing F2 on your keyboard. See this illustration below:

You can also check your backup settings to find the folder location of the backup file.

Here's how:

1. Go to the File menu, then select Back Up Company. 
2. Select Create Local Backup. 
3. Click the Options button.
   
4. Check the folder location under Tell us where to save your backup copies.
   

If you're still unable to find it, do a wildcard search on the computer. Type *.qbb (Back Up Files) in the search bar of the Start Menu. Make sure to include the asterisk (*) before the file type.

The result should show you where the last back up was and you can use it to restore the file to the new version. Refer to this article for more information about restoring a QBB file: Restore a backup of your company file.

If you need technical assistance, our representatives can check and walk you through the recovery of the files. Here's how to contact us:

1. Go to your QuickBooks Home page, then click the Help menu at the top.
2. Choose QuickBooks Desktop Help from the drop-down.
3. Hit the Contact us icon.
   

Let me know if you need further assistance, so we can perform additional troubleshooting steps to find your back up. Have a wonderful day!

How old is your "previous" version?
