Ok,
This is what I have found:
C:\Program Files (x86)\Common Files\ASCOM\Camera\sxCamera\
Loads of files here !
Also:
C:\Program Files (x86)\Common Files\ASCOM\Uninstall\Camera\sxASCOM\
There is an uninstaller here and it did completely remove everything from the above location and it no longer shows in SGP or windows uninstall thingy.
Cant find anything else !
Have a look for the above Uninstaller file, run it & see what happens Diesel
