This is from the POD Farm installation instructions - don't know if this helps, but here it is:
Default installation and Tone folder locations:
----------------------------------------------
• This version of the POD Farm software installs to:
Program Files (x86)\Line6\POD Farm 2
• The default location for Tone files is:
My Documents\Line 6\Tones\POD Farm 2.
64-Bit Plug-In Operation:
---------------------
By default, all POD Farm version 2.5 VST® Plug-Ins are installed within
Program Files (x86)\Line6\POD Farm 2\VST\Line 6.
****************
The POD Farm installer puts the 32 bit & 64 bit VST files in the same location.
I like to keep my 32 & 64 bit VSTs separate.
On my system rather than adding the Line 6 default paths to my scan folder list - I instead move the VST dlls to a subfolder of my choice that is located in my VST scan folder search path.
