Need to inplace update older versions of TV remotely
I have a corporate lifetime licence for TV 11 and have many remote box's using TV 9 & 10. I must get them updated to TV 11 before sept 15 2021 or I will lose control. When I try to use the auto update feature I get and error saying to check the logs, nothing in the logs help solve the problem as well as I don't think I can use TV 14 or 15 on these old machines or with my licence. I need to inplace upgrade to TV 11 but when I run the install I am told I have to uninstall the old version first and this can not be done remotely, the machines are embedded and have no display or keyboard or anyone around that can handle this. Can someone tell me how to manually do an remote upgrade to TV11? how does the auto update function work that it can do this?
Thank you for any help that can be provided,
