I'm having trouble compiling TI 73 assembly programs for Mallard.  I have practically no experience using a command prompt (I've only used mimas for assembly), so forgive me if I'm missing something obvious.

Here's the command prompt:

C:\asm>duck program
Compiling for 73...
TASM Z80 Assembler.       Version 3.2 September, 2001.
 Copyright (C) 2001 Squak Valley Software
tasm: pass 1 complete.
tasm: pass 2 complete.
tasm: Number of errors = 0
This version of C:\asm\Devpac83.com is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher.
Could Not Find C:\asm\program.73p
This version of C:\asm\asm73.exe is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher.

The computer popped up with a text box that said that devpac83.com is not compatible with 64-bit windows

devpac83.com and asm73.exe came with Mallard0.3

I don't know if there is an updated version of devpac83.com and asm73.exe or if there is a better way to compile programs for the TI 73, but if anyone has a suggestion, it would be extremely helpful.
Thanks!
