SPF-PC1 (16-bit DOS application)

For details of FRP supported environments, see KB81149.

The SPF-PC1 (16-bit DOS application) does not function correctly when the application runs under Windows and uses the ntvdm.exe application.

The number of files and folders displayed is incorrect when FRP is installed.

The DOS application can only function correctly and see its own files and folders after you remove FRP and restart the system.

DOS 16-bit applications are unsupported with FRP. For a support statement that covers 16-bit DOS applications, see KB75453.
