BTW I cannot find the 0x41 registry in the genesys files. So how can I go on ? Do you have any idea ? Do you know where I could find any technical documentation that I could use to understand what is going wrong ? Perhaps would I need to create a specific CIS_CANONLIDE700 but I really don't know how to handle it... Thank you for your answers ! -- next part -- An HTML attachment was scrubbed...
