Upgrading QB 2015 to QB 2019 - Error opening company file

Hi there, @Greg P. 

Welcome to the Community. I'm here to help and share some information so you can get past of the update message that you receive.

When you install a later version of QuickBooks Desktop, your company file is automatically updated the first time you open it with the later version. You'll need to make sure that you're the Admin to update the file. You are automatically logged in as the Admin user unless you have created users and roles in QuickBooks Desktop. To get rid of the error message, close the file and reopen it using the admin user login.

To learn more about the QuickBooks Desktop Admin role and with updating your company file, please refer to these articles: 

• Set up QuickBooks Desktop administrator and password.
• Update your company file with a later version of QuickBooks.

However, if the issue persists, I'd suggest giving our Technical Team a call. They have extra tools like screen-sharing to check on your file and verify on what's causing the issue.

To reach them:

1. In your browser, navigate to https://help.quickbooks.intuit.com/en_US/contact.
2. Choose QuickBooks Desktop.
3. Select the issue or topic.
4. Click the Green Phone button to see the support number.

This should help you get back on track, @Greg P.

Please let me know how it goes by replying into this thread. I'll be around if I can be of additional assistance. Have a lovely weekend!

I am having a different problem going from 2015 to 2019.  I followed all the screen prompts but am missing a couple of years (2017-2018) of data.  I am not sure how to fix this or where to go.

I am having a different problem.  I installed QB2019 with no problem and followed all the prompts.  However, all of my previous data is not complete.  I am missing the two most recent years.  Ugh.  Not sure how to move forward.

Hi there, @lighthousectr.
