Software Version 32 or 64 bit

I downloaded the free version of the Silverfrost Fortran, both Plato and FTN95. Am wondering what bit size version was downloaded and how to detect? The computer that I am executing on is a Win 10, 64 bit.

There is a single installer that includes tools for targeting 32-bit and 64-bit. The compiler generated 32-bit OBJs by default. With the /64 option, it generated 64-bit OBJS. There are two linkers, SLINK and SLINK64. Similarly, there are 32-and 64-bit DLLs for SALFLIBC, CLEARWIN, etc.
