Newbie first simple question(s)

[weer1]

Dear group,

On my assignment working with a CVS I choose WinCVS. The first simple
task is testing is locally. So I do what the manual
(http://sourceforge.net/docman/display_doc.php?docid=766&group_id=1)
tells me to. I went to 'Create new repository' and choose
:local:C:\cvsroot' for my CVSROOT. After choosing OK the error occurs:

cvs -d :local:C:\cvsroot init
Unable to initialize the CVS process: Het systeem kan het opgegeven
bestand niet vinden.
The CVS used is : cvs.exe
  (In English: The system can't find the given file.)

Given file? What given file? Anybody?
