Problem installing Trial Learning Voice PhraseBook Eng-Ita

In Windows XP SP3 I am installing the demo version of
LingvoSoft Learning Voice PhraseBook 2008 English <-> Italian.
It appears that the installation goes smoothly but when starting the application the main screen disappears after 3 seconds approximately.
My Windows Task Manager tell me that it is not running.

Thanks for Helping

Please close the application.
Make sure that it's not in the Tray.

Uninstall the Lingvosoft software from your PC. Please note, that all other software software products should be closed before you start uninstallation.
Once it's done? please restart you PC.
After that please go to the Start->Run option type "regedit" then Enter.
Go to the opened application to HKEY_CURRENT_USER Software folder and delete Ectaco folder from there.

After that please install the software once again.
Please make sure that all components are installed properly.
