Ok, under \ldclient\antivirus\kav I see the subdirectories for kl1_x64, kl2_x64, klif_x64_nt600, KLIFX64, and KLIMX64 so that makes sense.
I had first noticed that in task manager the executable was listed as "avp.exe *32" and after the install was done my definitions were old despite the fact that I included them in my agent config.
So it looked like it was only 32bit.
