Bitdefender fails to install requiring a re-boot.

I am trying to install a licence on a new laptop. The laptop has all its updates. After pressing Install on the the acceptance splash screen the software tells me that the PC needs a restart. If I press yes, the splash screen reappears and asks the reboot question. Press 'Yes' and the PC reboots. When the PC comes back and the install agent starts again it still insist the the PC needs a reboot. What is going on!
