I have been trying to get G2 working on Vista but getting the same da*n error I-controller could not be found. Not sure why? I checked the control panel and the I=Controller is listed, and in the properties It also shows the bars that correspond to each control, when you wiggle the controls the bars go up and down. This tells me that the controller and the driver is working OK. I looked at the installation and it is missing contents in the planes folder and the airport folder itself is missing.
Opening up the RealFlight Control Panel indicated "Not Installed" but shows up the serial number, most buttons are grayed out.
Any help is really appreciated
