The Assembly Registration tool reads the metadata within an assembly and adds the necessary entries to the registry, which allows COM clients to create .NET Framework classes transparently. Once a class is registered, any COM client can use it as though the class were a COM class. The class is registered only once, when the assembly is installed. Instances of classes within the assembly cannot be created from COM until they are actually registered.

Use 64-bit tools

This options specifies as whether to force the usage of 64-bit tools on a 64-bit system or not.  As FinalBuilder is currently a 32-bit application it will default to running the 32-bit version on a 64-bit system.  Check this option if you require the 64-bit version to be run.
