Update Skype manually

I checked software update information often. If there is new version come up, I will update it right away.
It is clear that Skype has a new version released. The one on my Windows 7 is I used Skype built-in Check For Updates function to check the new version. It said, no update found.
I go to the Skype official site, and download the Skpyesetup.exe file, re-install Skype program. It is still I don’t know what’s wrong of the Skype installation program.

I googled the new version download link. And found the full installation package. It is 30.5MB.
Download it and install it.
Check the about, it is now.
