When running the latest versions of Skype for Windows, Windows XP users are faced with a critical error, due to which the program forcibly stops its work.
Skype.exe - Entry Point Not Found
The procedure entry point CancelMibChangeNotify2 could not be located in the dynamic link library IPHLPAPI.DLL.
This error occurs because the last Skype installers for Windows are not designed for Windows XP and Vista, and even if you install and run these versions without errors, the correct operation is not guaranteed (as a rule there are problems with sound).
Since there is a specific installer that officially supports these operating systems, it is strongly recommended to select the right installer for your OS. You can download the correct installer from the following links:
Perhaps there are some updates or workarounds for Windows XP that add support for the CancelMibChangeNotify2 procedure to the IPHLPAPI.DLL library, but according to the information on the official site, this procedure is not supported in Windows XP. So if you want to solve the problem quickly, just download the right installer.
