I need to produce pdf files for turbo tax business, years 2004, 2003, 2002. I have the cds and tax files but they will not load or run properly. How can I create pdf??

Basically, you need to install that software on Windows XP or older. Then since you can't get the required updates for versions that old, chances are good that you will corrupt the .Tax20nn file from those years when you open them to create the PDFs. It just depends on the complexity of the business return. But after you open it in the program for that tax year, you can then elect to save it in PDF format.

It's possible that if you have access to a Windows 7 computer, you might be able to install those programs in XP compatibility mode. But you still won't get the updates needed to ensure accuracy.

You just learned the hard way why keeping PDF and/or paper copies of all returns is a must not a luxury.
