LANCommander supports the use of Detect Install scripts when installing redistributables. This type of script only serves the purpose to tell the launcher or SDK if a redistributable is already installed/available on the client's machine. These are useful to avoid installing the same redistributable that may be used for multiple games.
The result of a detect install script must be the setting of the variable $Return. This should be a boolean value and should equal $True or 1 if the redistributable is installed, and $False or 0 if it is not.
This example script was written to detect the installation of DirectX:
$Exists = Test-Path "HKLM:\\SOFTWARE\Microsoft\DirectX"
if ($Exists -eq $True) {
$Return = $True
} else {
$Return = $False
}
When a detect install script is executed, the following variables are available within the script:
| Name | Type | Description |
|---|---|---|
$Redistributable |
LANCommander.SDK.Models.Redistributable |
The redistributable's data object |
$ServerAddress |
string |
The source LANCommander server address |
