[JustoStyle]

Have deployed many of printers with this script but myself and anther coleege are having a issue with the script now where it produces this in the log file

and this in the event log.

It seems that the install cant find the INF file but i have checked and even decrypted the intunewin to check and the file is in there. Anyone else seen this it seems like an issue with intune deployment in general but posting there to see if anyone is able to assist.

Thank you,

What is the path of the .inf file, relative to the directory where install-printer.ps1 (or pnputil) is being called from?

Everything is in the root of the intunewim.

<System.InvalidOperationException: This command cannot be run due to the error: The system cannot find the file specified. at System.Management.Automation.MshCommandRuntime.ThrowTerminatingError(ErrorRecord errorRecord)>

This is generated by powershell when start-process isn't able to find an executable. It seems like it isn't finding pnputil.exe when it tries to start the process. Does your $env:path contain "C:\windows\system32"?

Consider adding 'write-log $env:path' to install-printer.ps1 before it tries to launch pnputil, so you know what's in it under the executing user's context (should be SYSTEM when run as device from Intune apps).

Does it work before packaging the .intunewin? What's the full powershell command calling install-printer.ps1?
What happens if you try to run pnputil manually? Does it successfully add it to the driver store?

pnputil.exe /add-driver su0emenu.inf

Running the script in its folder that gets packed into the wim. Runs fine the only thing i have noticed has started happening is it being up a box to trust the pusblisher of then driver.

Something seems to have change as if i upload a know working intunewim it no longer works and throws the cant find file path error above.

So maybe its something with how the intunewim is getting unpacked for new intunewims only.
