The last two updates to the game have locked up during the installation of the C++ libraries. I have to open the control panel and kill one of the 'three' processes that are running for 'cosmoteer'. That will kill them all.
When I click on the install window, which is all I see, it 'dings'. I suspect a 'window' is hidden behind it with an ok or similar button response that is it waiting for an input from me. But I cannot get to that window, even using the control panel. Afterwards, the game appears to work fine when I run it.
I have Windows 7 Pro 64-bit.
