I appreciate you for following the steps above, @Micheal01Y. 

As mentioned by 4Gal, may I ask which year version of QBDT you're using? Also, did you encounter any error messages while migrating your QuickBooks Desktop file? That way, I can provide a resolution on how to resolve them.

On the other hand, the steps shared in this thread will guide you in migrating your company file. However, if you've already performed the steps above, I'd recommend contacting our Customer Support Team. They can provide further troubleshooting steps to guide you in migrating your file and investigate this matter thoroughly.

Here's how you can reach out to them:

1. Go to Help, then select QuickBooks Desktop Help/Contact Us.
2. Click Contact Us.
3. Give a brief description of your issue, then select Continue.
4. Choose a way to connect.

When contacting support, you can check our available hours to ensure your concern will be handled promptly.

I'll also share these articles for further guidance in moving your file to another computer:

• Move or reinstall QuickBooks Desktop to another computer

Additionally, I’m adding these resources that can guide you on installing QBDT and how to handle installation errors with your new computer:
