Unable to open QBDT File

Do you only need to review the file or convert it to QB Online? Ask your client, which QB Desktop year version did they use?

I only need to review it. It looks like he did the back up this year, Im not sure if that means he had an up-to-date version or not

You can use the trial version of QB Desktop 2024 Enterprise to restore the backup file.

It's great having you here in the Community. Allow me to provide you with insights about opening a QuickBooks company file.

To start, you mentioned that your computer does not support QuickBooks Desktop (QBDT). Can you clarify whether your computer fails to meet the system requirements for QBDT? If that's the case, your computer needs to meet the specified system requirements for QBDT.
