The program features are useful. There are many free programs that offer similar features, but here everything is under one roof and works well. What a pre-reviewer has already criticized, is the way of activation. Usually, I use once a year on my machine and is intended to keep in mind that I should uninstall it before always. And, as has been criticized, it is completely impossible to uninstall the software if the system goes on strike due to a defect and you are forced to reinstall. But not only that, even if you only times installs a new hard drive, the activation is obsolete. The contact with Nuance's nice, but it's always a huge effort to ask for an increase in the activation count. You have to send a proof of purchase then - so definitely always keep the bill at hand (who is doing something really?) Or, alternatively, take pictures of the original CD with serial number label / scan. This is also accepted. I think it's great that I'll ever be stamped under general suspicion as pirates, then I might as well send a photo of the CD of the neighbors. Somehow all this is quite a nonsense. Finally, one must wait about a day until you can edit PDF files. For me, definitely a reason not to recommend this software and I will certainly change the next time to another manufacturer.
