Re: picgui issue
Thanks for reporting this issue. We are not performing tests with windows 8 but with windows 7. It seems most users are still with windows 7.
The registry seems different as the entry "HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM" does not exist causing this error. You might found workaround as such problems appears with others applications, but they seem complicated.
If you could provide few inputs about windows 8 registry structure nearby "HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP", we could probably fix the issue.
At least, we'll make the script more robust and provide the default COM1 to 255 choice if available COM port cannot be retrieved.
