Cannot install QuickBooks – problem in reading qbregistration.dat

Legacy KB ID: 3592

Question

Why do I get the message “Error: QuickBooks has a problem in reading this registration file: qbregistration.dat” when I try to install QuickBooks?  I have done a clean uninstall and reinstalled in selective start-up mode and I still get this error. 

Answer

This error will occur due to one of the following:
