Hi
Thanks for the response. Downloaded and installed your improved IDE but it still wont install the UNO driver. The uno still appears as unknown device with no driver. I have tried reinstall driver and selected the driver file from the new folder. Still no go. Since I am running Windows 7 (to my great regret) on this desktop I tried to install MS Framework 4.0 Since it attempted to repair it and the hung on me that doesn't seem much good either. I must say I am surprised that a system I have read so much about - Its ease of use for non electronics/non computer people - falls at the first hurdle. Whilst far from being expert I work with computers quite a bit and this is the first program I can remember which just plain don't work... Even all the PIC stuff has worked first time. All very disappointing.
