1
cab3.cab has an invalid digital signature

You can solve this error by explicitly trusting the certificate that the cab3.cab file was signed with, following these steps:

  1. Lookup up the file in explorer
  2. Go the file’ properties
  3. Go to the tab ‘Digital Signatures’
  4. Click the one item in the list en click ‘Details’
  5. Click ‘View Certificate’ in the openen window
  6. Install the certificate in the ‘Trusted Root Certificate Authorities’ store
  7. Re-run the setup, the cab3 exception should not occur any more

It complained about other cab files as well, but the installer would continue after just clicking ‘Ok’, otherwise you should repeat the steps for the other cab files as well.
