How can i run a 32bit program on a 64 bit windows 7

Could you give more details on the program? 32 bit programs should run just fine.

Also try right click and run in compatibility mode.

I have never had any 32bit program or game that would not run on Windows 7 64bit.
What program are you running?

a 32bit program that fix on a floppy disk(1.44 MB). What the exact error message?

Sounds like it's actually a 16bit program. which won't run (without an emulator) e.g. dos box

if it still on floppy it big chance it still use 16 bit/dos.... (as aab said emulator is needed)

normally 32bit will run fine in win7 x64........

except very old program like yours, unfortunately....
