[Updated 2018/10/25], Since TalkHelper v5.10, only Skype for desktop v8.x and Skype for business(32bit) are supported,
Skype UWP(Skype for Windows 10) and Skype Classic v7.4 are NOT supported any more.
You can download the Skype for desktop v8.x through the link below:
Note: Skype UWP version (Skype app from app store) looks extremely similar to Skype for desktop version, the only difference on the main UI between the two versions is the Skype icon on the title bar.
Make sure you sign out your account from Skype classic v7.41 or Skype UWP version before you login your account on Skype for desktop v8.x.
Skype for desktop version: (with Skype icon on the title bar).
Skype UWP version (Skype for Windows 10): (No Skype icon on the title bar)
