I never was asked and I have ez keys, Ez Drummer 2 and Ez mix. If you were it would have been for information only.

I have ez drummer and ez keys installed on my laptop and my desktop, for years. Which is perfectly fine with Toontracks. Linking the software to a computer ID code is the simplest way for companies to protect themselves.

You do NOT have to uninstall X3 either.
Most of us have Splat and CW splat installed side by side. No issues and that way your plugs are there also for Splat to use.
