you could finish the installation, that would probably make things run smoother.
the vicidial manual shows a lot of steps in installation. one of the phases includes installing the OS. after that you install vicidial. if you only perform the install os portion and skip the install vicidial portion ... it stands to reason that vicidial will not be installed.
so the question is, why did you not not follow the rest of the installation instructions? LOL
also: post the .iso version you are installing. there is a difference between the preload and standard versions of the .iso (as discussed in the manual ...).
i don't know if the manual for v5.0 is available on the vicibox site yet, but if you can't manage 5.0, step back to 4.0 which does have a pdf manual available.
PS: If you just want a simple answer, try entering "vicibox-install" and see how that works out. But DO read the install manual.
