Hi Krishna,
Error 193 usually means that non-windows application has been invoked on a windows platform. Non-windows sappfpar binary exists in the kernel directory
As per note above mentioned please confirm are there any non-windows executables for sappfpar (all sappfpar.* files except sappfpar.exe) exists under kernel directory (D:\usr\sap\ID6\SYS\exe\uc\NTAMD64).
If exists just remove non-windows executables for sappfpar.
Regards,
Gaurav
