DOSBox targets games, and doesn't provide full emulation of all DOS functions (such as file handling).

You best bet is to use a general purpose virtual machine to run non-game related apps. Or you can install that "Windows XP Mode" virtualizer which is available for Windows 7, it has NTVDM so you'll be able to run your 16-bit programs.

invalid handle.
Interesting error, but hard to say what goes wrong.

Maybe booting from a disk image would help?

How many cycles are you using? The error may be an overflow, triggered by a timing loop gone crazy. Try with less cycles and find what happens.
