I've installed it about one year ago on two machines, with some problems (don't remember exactly now) with registration on the second one, promptly solved with a mail exchange with DS team.
I like some of it's features, but dislike (or better HATE) the way you design new components and footprints.
Example: I've designed an 8 pin DIL connector, with some hassles being a novice, but searched through help for hours trying to find a way for modifying it to a 6 pin and save with another name.
The other problem is with the supplied libraries: searching through them is an big nuisance, and the graphic style of the components is inconsistent (line width, component style, ecc..) from one to the other.
Mi experience with PCB and schematic design dates back to DOS days, with PROTEL PCB and ORCAD schematics, but they were really more intuitive and, at the end, were doing the same service.
Cannot use those versions any more because they are outdated, and I do not have any printer that will work with Windows 98 anymore.
As my boards were becoming bigger and more complicated, I was obliged to use the services of external consultants, who use higher level CADs, but I would like to design again everything by myself
