How do I know that the installer was launched with the /quiet command-line option?

[Kostya]

Hello,

We use the Windows Installer "/quiet" switch to install silently:

Code: Select all

msiexec /i installer.msi CMDLINE="SOMEVAR=TRUE" /quiet

How would we know that it was run with "/quiet"?

I know, we can get and process variables in the code if we use CMDLINE, but I wouldn't want to pass another variable like that if the switch is present. As far as I understand, the predefined variable SILENT could be used if we run it like

Code: Select all

installer.exe /s

and does not help in this case.

Thanks,
Kostya

You don't need to worry about manually checking for that command line parameter.

When your MSI is launched silently, your setup will automatically receive the /s command line parameter from the MSI.

If this is not what you are seeing, please describe your workflow in detail.

John, you are right, I see that the SILENT variable works perfectly in the case described. Sorry, apparently I didn't check it correctly first here. Thanks!
