C=5 error when first installing

Legacy KB ID: 477

Question

When I first install QuickBooks I find an error message(C=5). What should I do?

Answer

This is related to the operating system that you currently have installed. It seems to happen only on a Win 98 machine. It is recommended that you download the lastest service pack from Microsoft and try again.
