Here's what I found from the Microsoft Tech website:
Thanks for the post.
Since Quickbooks was working fine in Vista,it should also work reliably on Windows 7.
However, you may like to follow these steps.
1. Right click on your quickbooks startup exe file and open properties.
2. On the compatibility tab select compatibility mode and run this program in compatibility mode for Windows Vista (Service Pack 2).
3. On privilege level check "Run this program as administrator". Press Apply/OK to close properties.
4. Start - Devices and Printers - add a printer - add a local printer - create a new port - local port and name it QBD_PDF.
5. Choose to install AMYUNI Technologies - Amyuni Document Converter 300 (click windows update button if it is not on your list).
6. If windows detects you already have a driver then choose to replace current driver. Name the printer Quickbooks PDF Converter - do not share printer - do NOT set as default printer. Finish
7. Start - Devices and Printers - Right click your QB printer, choose Printer - Properties and go to the advanced tab.
8. Remove any check marks in the 4 items with square boxes next to them (bottom part of screen) then select "Print directly to the printer" Hit OK to close the window.
9. Restart you computer and open Quickbooks. Open File - Printer Setup and make sure Quickbooks PDF Converter is the selected printer for any PDF operation you use frequently. (on rare occasions you may not see the Quickbooks PDF Converter on the list, reboot again and you will get it).
You can now perform PDF operations in Quickbooks (works for 32 and 64 bit Windows 7 RC)
