That's a problem with CV using DOS v2.X. CV uses the program name
passed to it by the EXEC loader of DOS (argv[0] to C programmers).
This wasn't available in DOS v2.X. Unfortunately, CV was build using
the name CVPCK, so it defaults to this when looking for itself in DOS
v2.X. Rename CV.EXE to CVPCK.EXE to get around this. (I would assume
that you could also use <your favorite binary editor> to patch CV.EXE,
changing the string "cvpck" to "cv<NULL><NULL><NULL>", but renaming
is easier than binary patches.) You could also enter the filename
CVPCK when it asks you for the new file spec in the prompt above.

On the same vein, another problem you'll run into is that when CV
looks for it's file CV.HLP (the help file), it can't find it under
DOS v2.X, since the Microsoft C Compiler startup code sets argv[0] 
to "C" under DOS v2.X, instead of the actual program name. CV looks
for argv[0].HLP, which works in DOS v3.X, but in DOS v2.X it looks
for the file C.HLP. The way to work around this is to rename CV.HLP
to C.HLP.

So, get a version of DOS above v2.X, or 

    C> ren cv.exe cvpck.exe
    C> ren cv.hlp c.hlp

until they release a new version.
