With this newest ESS 18.104.22.168 RC on my Win7x64 rig ESS installs in C\Program Files\ ... like it always has. The task mgr shows ekrn as ekrn.exe*32. I found an x86 folder inside the above location where ekrn resides. Since Nod32 was the only top-notch x64 native av available when XPx64 came out almost ten years ago I'm curious about this. Is the current av engine native 64 bit or not?
