推荐答案

1.)您无需注册jacob-dll，它只需要位于java.library.path上的某个位置即可.是包含必须注册的COM对象的dll.

1.) You don't need to register the jacob-dll, it just has to be somewhere on your java.library.path. It is the dll that contains the COM-object that has to be registered.

2.)如果已注册COM-dll，则必须注意在库中使用正确的JVM. 32位dll仅适用于32位JVM，64位dll仅适用于64位jvm.使用错误的JVM将导致Can't co-create object错误.

2.) If the COM-dll is registered you have to take care to use the correct JVM with the library. 32-bit-dlls will work only with a 32-bit-JVM, 64-bit-dlls only with a 64-bit-jvm. Using the wrong JVM will result in the Can't co-create object error.
