Comodo Dragon Setup "hangs" & won't finish

I installed CD. The installation track slowly filled up with green. When completely filled with green, the installation process “hung” and the installation would apparently not finish. The only way I could remove the visual installation interface was by going to the Task Manager, where I could force the running installation process to stop. CD seemed to be installed all right. But how can I do a proper installation without the suspended action at the end? I have Win 7 running on a 64 bit machine.

Hello,

Does this happen every time you try installing Dragon?
