Have you tried to install TBS 7 in Admin-Mode?

Yes, I tried installing as admin but no luck. Thank you for for your suggestion.

It is also possible that your security setting is too high or does not allow you to connect to the security http (https) setting. Try lower your security setting including internet security setting temporary for the activation. You may need to do more than once right away when it fails for the first attemp. If it still happens, contact support
