Not as complicated as feared and better than 11.5

Despite the negative reviews here, I have ordered the upgrade (as a download). Although the installation of the basic version ran long, but easily. After that service pack for 12.5 has been downloaded and installed as well. Finally, yet another for smaller version 12.5.1 has been recharged. The installation will take a total of endless and just before the goal then the message that any DLL missing and that I should install everything again but please, oh Nöh! So rather restart the computer and again the last small patches installed - and lo and behold, everything is going. Takeover of the old profile with no problems - no training required. And now the good: Dragon 12 runs not slower than 11.5 (despite Bestmatch V) and the accuracy is really much better - it is progress that is worth the investment.
Why only 4 points: The installation is a disaster - and if you forget to click on the Software Manager, the service pack is only to be downloaded (the tip can be found hidden somewhere on the homepage, but not discussed during the installation), then this is installed and then disappears into the depths of the system (may not be subsequently retrieved for security purposes again) = it must be downloaded again in case of any new installation (500 MB) and for how long this is possible is a matter of opinion. It is incomprehensible that a purchased download version is not up to date automatically. And still a minor annoyance: As always with Nuance any nonsense in the autostart is placed, then the persistent checks for updates, or registration of software expected - with small tricks are these things easy to disable.

Installed on a computer by 2010; Quad Core AMD Phenom II X4 920, 2800 MHz; Windows XP Pro, 4GB of RAM - truly not a muscle man (more).
