New Post: -ShowInstallationRestartPrompt -NoCountdown not visiable Version 3.5

I just found this project a couple of months ago and I think it's great work. I am still seeing the issue with the latest 3.6 builds from 3/4. I am using Altiris Notification Server and this is one of the last things to work out. Manually the prompt is there. It's also there from a Admin cmd box but it does not appear when pushed from Altiris.

Command-Line used => Deploy-Application.exe -AllowRebootPassThru -TerminalServerMode -DeploymentType Install

Script Snippet => Show-InstallationRestartPrompt -Countdownseconds 600 -CountdownNoHideSeconds 60

Error from log file.

These test machines are virtual boxes so I expect the warning about RDP sessions. Note, I have seen the same issue on physical machine. No restart prompt.

Is there anything I should be looking for to help track this down.

Thanks.
