dosemu v.0.99.10

[VirtuAlien]

Dear Sir or Madam,
    I have been having difficulty with DOSEMU v.0.99.10.  When I go to run 
"./setup-hdimage", I am told that /usr/bin/dexe/mtools (something like that) 
does not exist.  When I create the directory and file (dexe and mtools), I am 
given "Access denied".  I have mtools v3.8; could you please help me?  Thank 
you for your time.
