Read the stickied guide, but still have a question (never manually patched before, sorry)...

I've installed a 2nd copy of WoW (virginal 2.0 install just completed).

Can I just drag and drop the patches from our retail folder into my Den-only install?

Do I have to DL all the patches from pre-TBC (like from 1.01 or whatever the first one was) all the way up to 2.2.3 and install them?

If not, do I have to DL all the patches (like from 2.0.1 to 2.2.3) and install them in chronological order?

Or can I just DL the 2.2.3 patch?

Yeah, I know, I r teh techno-noob : (

Regards.

Edit: kids logged on to retail WoW with *my* pc and, as was to be expected, DLed the new patch when I had expressly asked them not to play on parental 'puter... I smell a suspension of their gaming privileges, hehe
