Quickbooks 2009 R9 Patch
If you’re running Windows 7 and Quickbooks 2009, do not install the R9 patch if it asks you to do so. It will break the PDF converter. This means that will no longer be able to sent invoices, statements, or reports in email. Also, there is some sort of issue with Sales Tax reporting in it as well. If you’re on Windows XP, everything appears to be O.K. Not sure about Vista, though.
