Good Day,


Microsoft Sharepoint Foundation Error

The above error occurred because, there is only one System.Data.Services entry, in the Global Assembly Cache version and it means the files are missing and that is the reason why MS Sharepoint cannot load.

Kindly follow the instructions from Microsoft to resolve this error, please see the links for your reference:

Take note of the Windows version you are using. You must download what is compatible with your current operating system version (Windows 7, Vista, Win XP, etc.)
