Hi @dony45.
I understand how important it is to have access to your QuickBooks company file. I can give you some information to help you get it downloaded.
We make every effort to provide customer support for registration and licensing for older versions of QuickBooks Desktop under Intuit's standard terms and conditions if that data is available.
Unfortunately, we can't guarantee we'll be able to register, provide key codes, or offer data and password recovery for older versions of QuickBooks.
You can download QuickBooks 2017 from our products download page, here. Once downloaded, you’ll need your license and product key available.
Thanks for reaching out to the Community. Let us know if you have any additional questions or can help you with anything else.
Take care!
