Install the client on pc with proxy configuration

Hello,

I'm deploying the cloud client to close to 500 devices.

Some of these devices are located outside the corporate network (are outsourcing personall assigned on other companies) so is not possible to use a AD directive.

I send to them the cloud installer and a script to remove any 3rd party av and do a silent installation, but the problem is that most of them have configured a proxy for internet access, so the installation process always fails (the error code is 143)

Is there some command to preconfigure the proxy server on the script ??

Right now the only way to continue is to do a request to the network admin to give temporal access to internet meanwhilw the installation finished, but is a process that in most cases could take a lot of time to tramit the premissions, so the idea is to find a way to include the proxy configuration before start the installation.
