Cyber Protect Deployment - Help

Hello,

I'm trying to setup a Cyber Protect deployment within datto.

I'm using the below script with variables :

Token
Username
Password

Cyber_Protection_Agent_for_Windows_web.exe --quiet --registration by-token --reg-token %token% --reg-address https://eu-cloud.acronis.com/ --agent-account-login=%username% --agent-account-password=%password%  

I go the strings by running --help

Anyone know why I'll be having issues? It simply doesn't install :)
Thanks!
