I can’t find the button for ENABLE from within the main program window
I don’t know how to do the activation

Downloaded, installed with zero problems. I just read some of the questions. To Activate – the first time you run it at the top right it shows a Key or Lic icon. After I installed with the keys, it doesn’t show and I doubt there is anyway to input it. As to the language, when you first install it, it asks for what language & defaults to English. After you install, run it and in the far right side it should have an language dropdown box. For both the questions if my suggestions don’t work, uninstall & install again – should be fine.

Downloaded, installed, and activated without apparent problems.
Not much play time as yet, but ACEPDF did a decent job of converting a short – but reasonably complex – PDF into a Word doc, with minor issues in font selection (some of the converted fonts were too closely spaced. Presumably could be fixed in Word). That alone makes this a program worth giving a try.

However – and as for all of the ‘bargain’ pdf editors tried to date – the process for Editing Text within an existing PDF is obscure / frustrating / poorly documented – take your pick. Again, ACEPDF is not alone in this.
Does not help matters that all Help / How To instructions are strictly on line, and (again) not as well organized (readily found) as they could be: they Exist, but one would want to Bookmark the relevant pages instead of fighting one’s way through their web site.

To be fair, standard of comparison is PaperPort Pro – not a “cheap” program – paired with OmniPage Pro (definitely Not Cheap). In combo, those can work very well, but they come with their own set of issues, so always keep an eye out for “simpler” solutions and will certainly revisit ACEPDF a few more time before deciding whether or not to keep it.

I installed it, tried to open it with regular crashes 5 times, disinstalled it….

Schönes Programm. Man braucht etwas einarbeitung aber das ist kein Problem.
