Comment 1 for bug 469312

So the VNC being disabled during install only happens if you choose a short password. You need to choose a longer password (6+ characters) for it to be offered. Perhaps rather than graying it out, we should just remove it from the page if you have too short a password to avoid confusion.

Can you please provide the files that you copied in place and the exact order all this happened so we can replicate the scenario and debug?
