As Abobe Flash support ends at the end of Dec 2020, the Crestron network interface will no longer work after that. Is there any solution for this?
As Adobe will no longer support Flash Player after December 31 2020, access to Flash Player will be removed from all browsers gradually, including Internet Explorer and Google Chrome. As a result, the Crestron RoomView service from BenQ, which is Flash-based, will also be discontinued. BenQ suggests using the following alternatives to manage and monitor multiple projectors.
1. Crestron RoomView Express: this software can be downloaded from Crestron’s official website.
