A timeout of 720 seconds is recommended.

Parameters

LabelDescription
Maximum Delay In SecondsMaximum random delay set to avoid network overload. Provide number of seconds lower than 600
Installer SourceProvide URL or UNC path to retrieve the installer file. Example values: http(s)://domain/folder/installer.exe, \serverSharedFolderwinrar-x64-571.exe
Installer HashProvide expected file hash using SHA256 algorithm to verify delivered installer file. E.g. FD820BF82EDBAA4BE20FD3B644A05754D95D71DE60FE79AB983C3318E0697540
Installer Signature ThumbprintSignature thumbprint to compare with the one obtained from the installer. E.g. CA0CE78818E27A35FA76F8857A1A163EF3679729
Install ParametersIf targeting a non-MSI-based application, provide optional arguments for the installer. Common parameter prefix and letters are allowed, such as /quiet, /noreboot, /s, etc. Provide "" otherwise

Outputs

None.

Restrictions

Further Information

The installer path could be either an UNC path with read access or an URL. The MSI error codes are documented here.
If the application is already installed, then it might be re-installed. Some user settings or application data could be lost.
If targeting a non-MSI-based application, it is frequently necessary to specify additional parameters for a silent install. In such case, please visit official documentation from the application vendor.
Be aware of whether silent install parameters are omitted, the install process may be waiting forever for user action while the remote action terminated before completion. In such case, you need to kill the process before executing the remote action again.

To get the signature thumbprint from a file, type this command on a Windows 10 PowerShell session and copy the SignerCertificate value":" Get-AuthenticodeSignature -FilePath <PATH_TO_THE_FILE>.
To get the installer hash, type this command on a Windows 10 PowerShell session":" Get-FileHash -Path <PATH_TO_THE_FILE> -Algorithm SHA256.
