I just started installing Team Foundation Server 2010 beta 2 from an ISO file, using MagicDisc to mount it in my Windows 2007 running in Virtual PC, while i stumbled upon this error:
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:
- Lookup up the file in explorer
- Go the file’ properties
- Go to the tab ‘Digital Signatures’
- Click the one item in the list en click ‘Details’
- Click ‘View Certificate’ in the openen window
- Install the certificate in the ‘Trusted Root Certificate Authorities’ store
- 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.
