In order to run Skype you must delete
$WINEPREFIX/drive_c/users/Public/Application Data/Skype
Why? Does this delete uc.tlb?
This path contains Skype's HTML login form - such HTML is currently not supported in Wine (bug 28457), thus you have to delete it.
This file is not in that path, I have no idea why Skype fails to open it.
I couldn't find that file in my Windows 8.1 and Windows XP SP3 installations either - it's possible that this file is embedded into Skype's binary and then it gets loaded on start up.
