Hi Mike,

I mentioned this in my 08:10 post yesterday: http://forums.dc3.com/showthread.php?p=21519#poststop "ASCOM Platform .NET Components 5.0" is an early title for the code that is now titled "ASCOM Platform 5.5 Updater".
Sorry; I read that but It didn't sink in.

I now understand how the ASCOM Platform 5.5 Updater became installed on my computer. Bob suggested on 15 September that I try this as a solution to the serial helper problems I was experiencing. http://forums.dc3.com/showpost.php?p=21299&postcount=2 so I did that.
Please uninstall the program titled "ASCOM Platform .NET Components 5.0".
I will uninstall the 5.5 Updater, but clearly my problems began before that was installed.
