Quickbooks 2007 has a nice feature to Save As PDF for various documents. This worked fine, but as soon as we installed Adobe Acrobat 8.1 Standard, whenever we save from inside of Quickbooks Acrobat the application pops up and complains we don't have a valid serial number. If you start Acrobat by itself, it says it is registered. It *is* a legal license.
Has anyone else seen this behavior and what is the workaround?
