CoronaSDK-2014.2189 will not install

Hi all,

I downloaded CoronaSDK-2014.2189 to my Windows 7 machine but it will not install. When I double click the .msi file I get a Windows Installer window on screen for ages saying “Preparing to Install” but after what feels like hours, nothing happens. I then click Cancel. It takes another age to cancel and then I get a message saying “Install server not responding”. Would any of you kind people be able to tell me where I am going wrong? Thanks! Eoin
