I was able to deploy silverlight using my scanning credentials with the following result command:
"{PackageShare}\\Installers\Silverlight\Silverlight_x64.exe" /q /noupdate /doNotRequireDRMPromptCan you do the following:
- Copy the Result command
- Replace {PackageShare} with the exact path defined under Deployment\Security options
- Paste the command into a command prompt on an example target machine and run it under the same credentials you are using to deploy.
This should help you to find the cause of the issue. Another option would be using the .msi and use the MSIuninstaller step. If you want to use the .msi you can extract it by running Silverlight_x64.exe /extract in cmd.exe. You can find more information on package deployment in
