Hi Masoud,

The problem is more about the Java you’re using, when you use a 64 bit JVM then you need to load 64 bit libraries (and so having a 64bit Micro-Manager). There is no way to load DLL from a 32bit Micro-Manager from a 64bit java. What you can do is have the 2 versions of Java (32bit and 64bit) then launch Icy with the 32bit Java when you need to load 32bit Micro-Manager.

Best,
