You should never assume that each and every Emacs feature will work on 
MSDOS.  Generally, only those features that are used by people who cared 
to make Emacs work on MSDOS were debugged to work there, and I would 
guess that none of them are vi fans ;-).

Please put the following on your Emacs init file (called `_emacs'):

(fset 'iconify-or-deiconify-frame 'ignore)

Then restart Emacs and try invoking `viper-mode' again.  The above magic 
should get you through that error, but I don't know if you won't bump 
into another problem further down the road (since I never use 
viper-mode).  If the above is all that is needed, please tell me so, and 
I will see to it that the next Emacs release will have this problem 
fixed.  If there are other problems, you will have to debug them.
