iTunes 6 + Multi-Plugin 2.3 + foobar2000 0.9.4.4

I have iTunes 6.0.5 with Multi-Plugin 2.3.2 and foobar2000 0.9.4.4

When i check "Use foobar passsrtough" it says that foobar is not installed (not found).

How to workaround this?

How MP detects foobar and how it works with it?

PS Switching to 7.0.5 + 2.5.1 is the lastest option.
