Hello,  
I’ve been using FMOD on a Unity project and it has been working fine until today I get the attached error. I am only trying to build the project for windows so I don’t know why its having a problem with Android. Any help on this issue would be greatly appreciated!  
Thanks, Rohan.

Hi,

What version of the FMOD integration are you using?
