can't integrate FMOD with Unity 4.6.1

I am using the free versions of FMOD Studio and Unity 4.6.1 and whenever I try to import a bank I get this notice that says FMOD Studio integration requires Unity 4 pro or Unity 5. Is there any way to fix this?

What version of the FMOD Unity integration package do you have? Version 1.06.00 and later will only work with Unity 4 pro or Unity 5. You can download an older version of the integration package here:

The newest one i believe. Thank you I will try that later this week.
