As for the DSI camera, I have uninstalled and reinstalled several times and rebooted the lappy many many times. I have installed the DSI through the supplied Meade disk, through the 'Add Hardware', through the 'Camera' section in Control Panel. I am totally out of ideas as none of them will allow the DSI to work in the program.
When I double click on the device icon down the bottom right of screen (where all the little icons are) a window opens and tells me what devices are in there. I click on the DSI and it tells me it is working fine

Then why can't the Invisage program find it???
