On first impressions (I had been using Design Spark PCB from its first version up to 6.1), I can say it is an utter POS.
Apparently it has some new authorization feature built in rather than the web auth. Like this is a "feature" that any user gives a flying feck about. Why does a free piece of software need authorization anyway?
Well, it appears to have broken it. I installed 7.0, uninstalled 6.1 manually after finding out DS doesn't do that automatically, then went to launch my lovely new version.
Yes, it does this within a fraction of a second of trying to launch it. No option for re-registration or anything. Yay! Way to go RS!
This new "feature" is just what the world has been crying out for. I'm going to go with Chris Gammell and his endorsement of KiCAD.
