I got a notification for upgrading to newer version when opening Skype on my Windows 8.1. But when I chose to upgrade, it stopped at this error complaining “The older version of Skype cannot be removed. Contact your technical support group.” Ok, well. What if I manually remove the old version from Windows Programs and Features? Boom, another stop error “Can’t find Skype.msi in folder C:\ProgramData\Skype{4E76FF7E-AEBA-4C87-B788-CD47E5425B9D} for the corresponding version”. Can’t continue the upgrade process.
After some Bingle, looks like this is a common issue after installing certain previous version of Skype. According to this article, I have to update Skype without using any Skype installer. But when I downloaded the Skype full installation file directly from Skype.com, it is a Skype installer exe. I was not able to find the msi file as the solution mentioned. Then I just thought how about going to the folder windows installer was complaining about. Bingo, found another folder in C:\ProgramData\Skype{7A3C7E05-EE37-47D6-99E1-2EB05A3DA3F7}. And the new version of Skype.msi is right there. Then I just used 7-zip to open this msi as an archive. And copied Skype.exe to overwrite the old version of exe in the program files folder. And the upgrade is just done! Started the Skype, checked the version. And it shows the new version number.
