Q: I have purchased Toontrack EZdrummer from Sweetwater; I have it installed on my studio computer, but would also like to run it on my laptop. How many computers can I install it on at once?

A: Toontrack's copy protection system allows you to have active authorizations on up to two computers at once. If you replace a computer or want to move the software to another machine, you can use the Toontrack website to de-authorize a computer, then authorize a new one. This can be done for a total of four computers. After you've used four authorizations (two at a time), you'll have to contact the company directly if you need to move the software to another computer.
