I am trying to install applications using powershell that require command options be passed to them. Normally this does not seem to be a problem however one I am working with is not running for me.

$InstallFile = "\\server\public\Windows\application_setup.exe"
$InstallOptions = "/VERYSILENT /LOADINF=\\server\public\Windows\Setup.ini"
& $InstallFile $InstallOptions | Out-Null

It generally will take one option or the other depending on which is first, but fails to take both. I have done this with single and double quotes and get the same problem both ways.

Try using Start-Process:

$file = "\\server\public\Windows\application_setup.exe"
$arguments = "/VERYSILENT /LOADINF=\\server\public\Windows\Setup.ini"

Start-Process -FilePath $file -ArgumentList $arguments -Wait

Thanks for the reply. This seems to suffer from the same problem. Since your solution seems to work the same way mine did I did a little more research and testing and am noticing that the problem even occurs at the command line so this is not a problem with PowerShell but with the syntax of the command itself. When I use a location such a c:\temp\setup.ini it works fine. It also works fine when pointing to a mapped drive. It just does not work when using the UNC path in the LOADINF= statement. I will copy the ini file to a local drive using the script and call it from the local path. Again thanks for your help.
