MDI AD Sensor - Unable to install silent with proxy parameter

Question

Hi, I'm trying to install the ATP sensor for MDI on our AD. The installation through the GUI setup.exe failed with an error code leading to the our use of a proxy. I am now trying to install it through the silent install using CMD with the proxy parameters and the following command, but the installation does not seem to work at all:

"Azure ATP sensor Setup.exe" /quiet ProxyUrl="<ProxyAddress>" NetFrameworkCommandLineArguments="/q" AccessKey="<AccessKey>"

Here is the log file I'm getting out of the installation, with censored proxy address:

Any idea what could cause this ?
