How do i use a back up to bring my desktop data online?

I've got some troubleshooting steps you can perform to fix the desktop crashing issue, poolmanfla-outlo.

Let me share some possible reasons why QuickBooks Desktop stopped working:

• You may have a damaged or missing QBWUSER.INI file
• You may have corruption on your hard drive
• Your program files or QuickBooks Desktop installation may be damaged
• You may have a damaged Windows operating system

To fix the issue, you can run the Quick Fix my Program from the QuickBooks Tool Hub. This will run a quick repair on your program. Here's how:

1. Download and install the latest QuickBooks Tool Hub.
2. Once done, open the file and select Program Problems.
3. Select Quick Fix my Program.
4. Start QuickBooks Desktop and open your data file.

If the issue continues, use this article for more troubleshooting steps to help fix the issue: Fix issues when QuickBooks has stopped working. 

If everything looks good, you can move your QuickBooks Desktop data to QuickBooks Online. Here's an article you can use for the process: Move your QuickBooks Desktop file to QB Online.

Note that since you're using an older version of QuickBooks Desktop, the steps may or may not work for you.

You may also consider opening your backup copy to our QuickBooks Desktop testdrive and transferring your file from there.

I'm also sharing this link to know the limitations when migrating Desktop data into QB Online.
