Why does it reply "Failed to load function! KERNEL.32.dll GetLogicalProcessorInformation"?
That means your Windows XP hasn't been upgraded to the Service Pack 3 which is the minimum requirement for Skype to be installed on your computer. The error is generic for Service Pack 2 installations. However, I wouldn't recommend keeping Windows XP anymore because it is old and no longer supported by Microsoft. Install Windows 7 or higher if you have the chance to do it.
