onOne Software’s Perfect Effects 8 available for free

Before I install it, can someone tell me more about this software?

How big is the installation? I don’t have Lr or PS.

Are there services running in the background even if I don’t run the software? e.g. DRM, Update, etc

Review on Amazon isn’t so exciting. I understand this is FREE but there are a lot of harm a bad software is capable of doing.
