On my laptop, I install windows xp because it is user-friendly for me. However, Skype cannot be open because “The system is not unavailable”. At last, I find the “Skype” directory under “C:Documents and SettingsAdministratorLocal SettingsTemp” cannot be accessed. “C:Documents and SettingsAdministratorLocal SettingsTemp” is like temporary directory for specific user under Linux OS.
Actually, for this question, we often think we need to force remove “C:Documents and SettingsAdministratorLocal SettingsTempSkype” dir and re-build a new one. Unfortunately, we cannot force-remove it for some reason. At last, I reset user Temp dir path as follows.
1, Right-click ‘My Computer’;
2, Choose ‘Property’;
3, Click ‘Advanced’ to reset Temp dir.
