16-bit MS-DOS Subsystem Error Message

Some users with Windows XP or Vista , have experienced problems when attempting to install or run DesignaKnit 6 or 7, or Fittingly Sew for Windows.

A Windows error message entitled 16-bit MS-DOS Subsystem warns you that the program you are attempting to run (DesignaKnit or Fittingly Sew or the set up for either program) is not suitable for running on a 32-bit system.

This is not actually the case, but it is an error known to Microsoft and is the result of the deletion or corruption of some system files which are essential for running 16-bit programs. The fault probably occurs during the installation of some third-party software or device driver.
