Adobe Air ANE support multiple dll dependents?and 64bit dll?

Recently,I was trying to develop an ANE on Windows to extract some customized exif info from jpeg file.The native library depends on some other dlls. I followed the instructions from the official tutorials,but never succeed to get the ane work.I tested with a single dll native library,succeed.So I wonder wether Adobe Air ANE supports multiple native library.And if it does,how?

Another problem is that I found only 32bit FlashRuntimeExtension.dll, that means I cannot build an ane with 64bit native library on windows. Am I right?

I googled and searched on the forum,but failed to get anything useful.If it is so difficult to extend adobe air with native code,I have to find an alternative framework to build my desktop application.Anyone knows anything about this,pls help.Thank You!.
