.Net framework installation showing error message

Hello! I recently installed parallels in my Mac and my computer running on Windows 7. Now, I need to install an application that requires NET Framework. While I tried downloading the NET Framework from the Microsoft’s website but I keeps on getting the error message saying “C:UsersAdministratorAppDataLocalMicrosoftWindowsTemporary Internet FilesContent.IE55SOFW5UAdotNetFx40_Full_setup.exe is not a valid Win32 application". Do any of you know how to solve this issue? I really need your help. Thank you.
