Help with the New Skype

So, Hello, to make the story short, let just say that my "Windows Installer Package" have problems, so I couldn't install the Skype Updates from the original website[had Skype version 5 - The old version when Ebay owned it]. so I found this website and started using Skype Portable - which didn't need any installation using the Windows Installer Service, I've installed version 6.06 at the time. each update I was downloading a new version from this website, a portable version and everything went smooth, I have to honor you on your great job, although, when Skype 7 Portable finally came live, I downloaded the installation file, but I couldn't install it, because it seems that this version is using the Windows Installer Service, which i can't use.

is there a way to override this? get only the Skype files without any installation (might this work?) Thanks
Neyney.
