Just a follow up from my previous post above.
Firstly On1 crashes when loading a picture, and trying to remove this software is a real pain, To uninstall it again you need to deactivate it which must be done within the program BUT since the program crashes before you can actually open and access the menu its very difficult to remove this. I had to use system restore to get rid of it.
So be careful when installing this or don’t install in the first place.
To sharewares defence I don’t think they can be blamed for this as its the installer that is faulty.
