Recently I’ve had several calls from people getting an error when trying to open the payroll tax forms. The exact error may vary, but it will be similar to The procedure entry point…could not be found in the dynamic link library…\Formviewer\Aatrixforms.exe.
The problem can usually be fixed easily by reinstalling the Aatrix form viewer. Just download the file Peach.exe from https://aatrix.com/sage50accounting and then run the file to reinstall the tax forms. That has fixed all the cases I have encountered recently. But if that doesn’t solve the problem, you can find additional steps in the Sage 50 knowledgebase.
