<summary>Getting the install files for ASM Web Servers with Direct Connection to the Internet- PowerShell Script</summary>

Run PowerShell V5 or later as an Administrator and execute the following script:

{% code overflow="wrap" %}

```powershell
Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope Process -Force; Invoke-WebRequest "https://alembareleases.blob.core.windows.net/asm- core/hermes_latest" -OutFile "$env:TEMP\Download_ASMCore.ps1"; Invoke-Expression "$env:TEMP\Download_ASMCore.ps1";
```

{% endcode %}

<summary>Getting the install files–Non-Interactive Installation For ASM Web Servers without direct connection to the Internet</summary>

Use this approach if the server which hosts your ASM application, commonly referred to as the ASM Web Server, does not have direct connectivity to the internet.

**Best Practice: Use the AlembaSetup.exe&#x20;***<mark style="color:green;">**Contact Alemba Support for this file**</mark>*

If you choose to progress the installation manually, you will need to perform the following:

1. In this case, all parameters must be set either as machine level environment variables or must be added to the registered key vault before install.ps1 is executed.

{% code overflow="wrap" %}

```powershell
[Environment]::SetEnvironmentVariable("ASM_ConnectionString", "Server=localhost;Database=asm;User ID=sa;Password=password", 'Machine')
```

{% endcode %}

2. Download package.zip and install.ps1 and copy these files to the same location on your server. (For example, an 'install' folder on the root or in a new folder you create for these files in the location you choose.)

You can download the files manually from here:

* <https://alembareleases.blob.core.windows.net/asm-> core/\[BuildNumber]/package.zip
* <https://alembareleases.blob.core.windows.net/asm-> core/\[BuildNumber]/Windows-Install.ps1

The \[BuildNumber] can be found in the Release Notes e.g. “HERMES *10.6.6.11415*”

3. Run PowerShell as an administrator and execute Windows-Install.ps1
   * Navigate to the folder where installation files are (making sure they haven’t been locked in any copy process)
   * **Best Practice:** Use AlembaSetup.exe
