powershell script error

Try changing the SecurityProtocol command to this
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Thanks, I tried that, but apparently I'm still doing something wrong.

This is the command I executed:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 $WebClient = New

-Object System.Net.WebClient; $WebClient.DownloadFile("https://download.newrelic.com/install/newrelic-cli/scripts/instal

l.ps1", "$env:TEMP\install.ps1"); & PowerShell.exe -ExecutionPolicy Bypass -File $env:TEMP\install.ps1;   $env:NEW_RELIC

_API_KEY='NRAK-xxxxxxxxxxxxxxxxxxxxxxxx'; $env:NEW_RELIC_ACCOUNT_ID='zzzzzzz'; & 'C:\Program Files\New Relic\New Reli

c CLI\newrelic.exe' install

This is the new error message:

Unexpected token 'WebClient' in expression or statement.

Add a semi-colon after Tls12 and before $WebClient

The semi-colon is required to separate the statements....probably a copy paste issue ;-)

Hi!

Here is an updated code with error handlers. I have included notes in the code for your reference. It should work now. Do let me know if there is an error that appears.

try {
    # Set the desired SecurityProtocol
    [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

    # Download the installation script
    $WebClient = New-Object System.Net.WebClient
    $installScriptPath = "$env:TEMP\install.ps1"
    $WebClient.DownloadFile("https://download.newrelic.com/install/newrelic-cli/scripts/install.ps1", $installScriptPath)

    # Execute the installation script
    & PowerShell.exe -ExecutionPolicy Bypass -File $installScriptPath

    # Set the environment variables
    $env:NEW_RELIC_API_KEY = 'NRAK-WVxxxxxxxxxxxxxxxxx'
    $env:NEW_RELIC_ACCOUNT_ID = 'xxxxxxxx'

    # Check if the New Relic CLI executable exists
    $newRelicCliPath = "C:\Program Files\New Relic\New Relic CLI\newrelic.exe"
    if (Test-Path $newRelicCliPath) {
        # Install New Relic using the CLI
        & $newRelicCliPath install
    } else {
        throw "New Relic CLI executable not found at '$newRelicCliPath'."
    }
}
catch {
    # Handle any exceptions that occurred during the script execution
    switch ($_.Exception.GetType().FullName) {
        'System.Management.Automation.RuntimeException' {
            Write-Host "Error connecting to database: $($_.Exception.Message)"
        }
        'System.Net.WebException' {
            Write-Host "Download error: $($_.Exception.Message)"
        }
        default {
            Write-Host "An unexpected error occurred: $($_.Exception.Message)"
        }
    }
}
finally {
    # Clean up the installation script if it was downloaded
    if (Test-Path $installScriptPath) {
        Remove-Item $installScriptPath -Force
    }
}

I tried again with the semicolon, but it's still failing, the command is in black, the error is below.

Seems like you're using PowerShell 2.0.
The last Windows version that came with PS 2.0 was Windows 7 / Server 2008 R2, so either your OS is really old, or you're starting PowerShell with the "-Version 2" parameter, for whatever reason.
What's your OS, and what's the output of

$PSVersionTable

Select allOpen in new window

You can install PowerShell 5 even on Windows 7 (though Windows 7 shouldn't be online anymore, but you probably know that):
Install and Configure WMF 5.1
https://learn.microsoft.com/en-us/powershell/scripting/windows-powershell/wmf/setup/install-configure?view=powershell-5.1

And any specific reason why you're squeezing that into a single line?

I am running windows 2008R2.  I just copied and pasted the code from new relic, so not sure why its' on the same line.

So you're saying to upgrade powershell to v5?

This is the error message I get now:

I only posted the full script for reference, not for another attempt; you can't run that script in PS 2.0, full stop.
Download the msi using a browser, install it, run only the last three lines of the script, like I described above.

Got it, I did and that would work, but I got this error message, it looks like they don't support windows server 2008 R2, which is a bummer, as I still have 5 or6 or so VMs running this OS.

I have sent an email to support to see if they have a different installer that supports this OS.   Thanks for your help

We encountered an issue during the installation: there was an error discovering system info: Insta

rror: This version of windows is no longer supported.

If this problem persists, visit the documentation and support page for additional help here at htt

Noah, I tried the script, but I'm still getting errors with it.

I was able to manually install an older version of the client on the server.  Now when I went to activate the API key, I get this error now. This is never ending.

I must be missing something from the code?
