UPDATE: It is possible to install ColdFusion 9 on Windows 7. Thanks to Paul Kukiel and Terrence Ryan for very quickly pointing this out. Paul points to this blog entry to explain the process.
After attending cf.objective() ANZ I was keen to spin up the release version of ColdFusion 9. I have recently migrated my main environment to Windows 7, and try to run my windows virtual machines in Windows 7 as well.
As you can guess from the post title, ColdFusion 9 is not supported on Windows 7, and indeed during the Web Connector installation on my Windows 7 virtual machine things went pear shape. Technically Windows 7 is very similiar to Vista, but I guess Windows 7 might ship with a new version of IIS which causes problems.
No doubt these problems are surmountable, but in the end I didn't try. I created a Windows XP virtual machine instead. This is another reason why having the capacity to run virtual machines, in my case VMWare Workstation 6.5, is a real boon.
