I have managed to download the application to install it. I actually downloaded the whole CD with the drivers. The CoolingTech application installed normally without errors. However, there is a trick, although the application can be installed, it won't detect the microscope in Windows 7 32 or 64bit mode. Because of that, you are forced to use CamApp. There is nothing you can do to make it work. I have tried every possibility except virtual machines.
Download the CD through Google Search and then the Hw2sw website: http://goo.gl/2k8CfU
