We recommend that you upgrade to a later supported version of Microsoft Visual FoxPro. Tests show that the later versions don't incur this problem.

DOS 16-bit applications are unsupported with FRP. For details, see KB75453 - Support for 16-bit DOS applications with File and Removable Media Protection.

NOTE: These older 16-bit FoxPro modules aren't supported because they can't be debugged with modern Microsoft debugging software. Only the later 32-bit and 64-bit Visual FoxPro versions are supported.
