Warning: your system hasn't been patched against critical Windows security vulnerabilities
If you have the first error, this is because you are using an old version of Windows 7, that does not support SHA2 code signing, which is now required by a Microsoft policy for new drivers signing certificates. There is no way around that, you will have to make sure your OS has the last security updates.
To fix both of these errors, make sure you apply the latest security updates from Windows update. If you are unable to use Windows update, you can get them from Microsoft website:
We are aware that some people using cracked versions of Windows are unable to apply any updates because their OS has been modified. There is nothing we can do about that, you will need to reinstall a version of Windows where updates are working properly.
