P99 and Full version

[LeorickEci]

Is it possible to have both P99 version of EQ installed as well as the current SoE version? I tried installing the Steam client version, but when I tired logging into P99, it was using the Steam drive to load up from for some reason, giving me all kinds of errors, stating it needed to be updated, etc.

Now I'd like to pop into EQ vent out my anger and frustration in zones that I keep getting killed because of trains or people with bad pulls, and wipe out that zone with my level 70s. Then return back to 99 and enjoy the game as it used to be, when I had the most fun.

So far a couple of tricks I tried doesn't seem to work, P99 keeps finding the steam client.
