Hi, I’ve got source that uses FMOD Ex which I need to port from 32 to 64 bit Windows. For what I’m doing 32-bit compatibility won’t work. Sadly, for this API I can’t locate any 64 bit static library. It seems the 64-bit statics were only built several version later. Assuming I can’t get this 64-bit library for Ex, I will need to update the source to a later version.

I don’t know which version I have, I only see “FMOD Ex - Main C/C++ header file. Copyright ©, Firelight Technologies Pty, Ltd. 2004-2010.” and #define FMOD\_VERSION 0x00011000

I’m struggling to find anything which helps me migrate from an Ex API to a more recent one, especially wrt FMOD::MusicSystem which no longer seems to exist (functionality in event system?)

Any help hugely appreciated.

Thanks,  
Phil

you can try loading an fmod designer project into fmod studio, and there is a guide for migration from ex to studio at [https://www.fmod.com/resources/documentation-api?version=2.0&page=white-papers-transitioning-from-fmodex.html](https://www.fmod.com/resources/documentation-api?version=2.0&page=white-papers-transitioning-from-fmodex.html)
