Informally, assuming your emulated environment is working correctly, are
you missing DLL files?  Perhaps the error you're getting (Look it up) may
be at the VB4 interprer level, if DLLs were missing, as a catch all DIE
abort sequence.    There may be a way to get verbose errors by using a
switch at the command line when you run the program.

Does this program load and run on a vanilla win NT/95 or other
VB4-compatible system?  If it does run on a real machine, compare the DLLs
there with your virtual machine.  There may be a set of DLLs that need to
be copied over, too for the program to operate.

If not Win NT or Win95, does it work on Windows 3.1?  Win 2000?

You could attempt to hexedit the executable.
