    To solve the issue, you should run system file checker. System files checker replace corrupted files and make them genuine. Follow the procedure:

    -> Go to start button and click on All Programs
    -> Navigate to Accessories and right click on command prompt
    -> Click on Run as administrator (Type password if required)
    -> Write sfc /scannow on command prompt and hit Enter

    This process will scan all files and will replace incorrect versions to genuine one.

    If you are not getting resolution then follow another method, after opening command prompt as processed above:

    -> Type takeown /f Path_And_File_Name
    (eg: takeown /f C:\windows\system32\jscript.dll)
    -> Type icacls Path_And_File_Name /grant administrators:F
    (eg: icacls C:\windows\system32\jscript.dll /grant administrators:F)
    -> Type Path_And_File_Name_Of_Source_File Path_And_File_Name_Of_Destination
    (eg: C:\temp\jscript.dll C:\windows\system32\jscript.dll)
