' USER SETTINGS
'
'

' SetupVersion
'    Setup version with the pattern <major>.<minor>.<release>[-<package>]
'
SetupVersion = "1.2"

' When using a nightly built version, uncomment the following SetupVersion definition line
' replacing gitABCDEFGH with the most recent git revision found on the nightly builds site
' In that case, SetupNightlyLocation will be selected as location in place of SetupLocation
'SetupVersion = "1.0-gitABCDEFGH"

' SetupLocation
'    Depending on your needs or your environment, you can use either a HTTP or
'    CIFS/SMB.
'
'    If you use HTTP, please, set to SetupLocation a URL:
'
'       SetupLocation = "http://host[:port]/[absolut_path]" or
'       SetupLocation = "https://host[:port]/[absolut_path]"
'
'    If you use CIFS, please, set to SetupLocation a UNC path name:
'
'       SetupLocation = "\\host\share\[path]"
'
'       You also must be sure that you have removed the "Open File Security Warning"
'       from programs accessed from that UNC.
'
' Location for Release Candidates
SetupLocation = "https://github.com/glpi-project/glpi-agent/releases/download/" & SetupVersion

' Location for Nightly Builds
SetupNightlyLocation = "https://nightly.glpi-project.org/glpi-agent"


' SetupArchitecture
'    The setup architecture can be 'x86', 'x64' or 'Auto'
'
'    If you set SetupArchitecture = "Auto" be sure that both installers are in
'    the same SetupLocation.
'
SetupArchitecture = "Auto"

' SetupOptions
'    Consult the online installer documentation to know its list of options.
'    See: https://glpi-agent.readthedocs.io/en/latest/installation/windows-command-line.html#command-line-parameters
'
'    You should use simple quotes (') to set between quotation marks those values
'    that require it; double quotes (") doesn't work with UNCs.
'
SetupOptions = "/quiet RUNNOW=1 SERVER='http://glpi.yourcompany.com/front/inventory.php'"

' Setup
'    The installer file name. You should not have to modify this variable ever.
'

' Repair
'    Repair the installation when Setup is still installed.
'

' Verbose
'    Enable or disable the information messages.
'
'    It's advisable to use Verbose = "Yes" with 'cscript //nologo ...'.
'
Verbose = "No"

' RunUninstallFusionInventoryAgent
'    Set to "Yes" to first uninstall FusionInventory Agent
'    Also and unless SERVER or LOCAL are defined in SetupOptions, this script
'    will try to get them from FusionInventory-Agent configuration found in registry
'
