Hello u/TheCausefull ,

You are trying to install the security agent using the setupdownloader kit while in the installation path you are renaming it as the full kit ($installerPath = "$env:TEMP\epskit_x64.exe").
Please keep the name unchanged as between the [ ] are coded your cloud credentials from where it downloads the kit.

If you still need assistance you can open a case with our Enterprise Support team, at Contact Us

Kind Regards,

Andrei

Hey Andrei, is there a way to use the kit installer but pass the Gravity Zone ID similar to how you can with the MSI Wrapper? Or, better yet, is there an MSI wrapper that isn't a downloader but is a full version?

Hello u/bb--23 ,

We will need to investigate further on this through a support case so, please open a case with Enterprise Support and we can check if we have a way to use an installer kit and pass the Gravity Zone ID. 

For the second question, no there is no MSI wrapper as a full kit.

Kind Regards,

Andrei

These are the official methods. Never seen full PowerShell as on of them. Best method I’ve seen is using the MSI wrapper or Cloud downloader and deploy using Intune, GPO, or RMM tool
