Windows Validation fails with errors
The message may also be accompanied with validation error codes: 1699978131, 1571607440, 757834664 or 228668481! Specifically, this issue could occur when you try to install Multilingual User Interface (MUI) packs on Windows 7 Starter, Home Basic, Home Premium, or Professional edition. Multilingual User Interface (MUI) packs require a license to be used and are available only for Windows 7 Ultimate and Windows 7 Enterprise editions. If these language files are present on another edition of Windows 7, genuine technologies will detect tampering on the system and display the non-genuine warnings. To resolve this issue you will have to remove the MUIs or reinstall Windows 7.
