I have tried to install this verson of skype (Skype Portable 5.3.0.111) on my flash drive (Kingston 8GB) and it was telling me that there was a problem with the program itself as in the install package itself was corrupted. I tried again and the same thing. Then i completely uninstalled the app and tried to reinstall it....still the same problem. Somebody please help me (or if there is more) us.
We need the exact error message to assist you. Offhand, it could be that you are blocked from skype.com at your current location, so you simply can't install it there.
Sometimes, the impossible can become possible, if you're awesome!
maybe you got a bad download where it was missing just a sliver of bytes and it was corrupted?
