EditVoicepack will not put an icon on the desktop, as this is against Windows installer guidelines.
To start EditVoicepack:
- press the windows key
- Start typing: EditVoicepack
- As soon you have typed enough, EditVoicepack XL will show up as an App. Click it to run it.
You can also press the windows key and scroll trough the list of applications yourself, but personally I find it a lot easier to start typing.
