If this product was written using Microsoft's math coprocessor emulation routines (which will emulate the xx87 if not there and will use it if it is there) then it should be possible to turn off the coprocessor by defining an environment variable named NO87 and setting its value to 0 or 1 or anything else you like. It's mere presence is enough to force the emulation routines to ignore the xx87. This is documented and works in Microsoft C, and I think it also might work with their other languages. Fred
