Hi thewall58,

We appreciate your interest in purchasing older version of QuickBooks. However, QuickBooks Pro 2001 version is no longer supported. And, we're no longer distributing CD installers of it.

Let's try to wait for other users to jump into this thread. They might have a few pieces of advice where to get an installer. 

Please also check out our website if you wish to upgrade to the latest version: https://quickbooks.intuit.com/desktop/pro/.

Have a great day!
