I downloaded the new version of Skype 220.127.116.11 from skype, but it pops up an error during installation. Below is a link to a screenshot:
Most likely this indicates a problem with installation of Skype Click-to-Call add-on. There is a bug in this installer that prevents installation on a non-English version of Windows. I guess that yours is Polish.
You don’t need this add-on for normal use of Skype.
You can try to install Skype using this msi-installer for the currently latest 18.104.22.168 version. Click-to-Call is not installed using this msi-installer.
