It shouldn't interfere at all. It's a completely separate game. Even with Live Everquest the patcher shouldn't interfere, speaking form experience as I have Live, EQMac, and two EQEmu clients installed myself. That is, unless you have the patcher directed at your EQ folder (why you would do this for a Vanguard install, I haven't the slightest clue).
I'm certain the error you receive is an issue dealing with an incorrect install or a bug on SoE's part. I would direct this issue with them or double check how you have the patcher etc set up.
