I already registered. Why do I have to do it again?

The DFX software license allows installation on multiple machines as long as only one copy is in use at a time.

If your usage falls under these guidelines, then you can install DFX on multiple machines. Keep in mind that each machine needs to be registered individually using your Serial Number.

If you haven't changed machines, then any system change that requires reinstalling DFX will cause you to have to register again.

Please don't distribute your Serial Number as it may prevent you from using the software in the future.
