The slicer is built in my Mac of x86_64. When I try slicer to install extend module, it could find HammerRegistration and installed. But when I restart Slicer, I can not find HammerRegistration module. I guess whether the website only provide precompiled 32-bit HammerRegistration. If so, could you please let me know whether you provide 64-bit HammerRegistration for Mac or how to get the 64-bit library from your open source codes?

Thanks,
