HP Image Assistant Fails During Silent Driver Installation

Hi everyone

I've been trying to automate HP driver update using the HP Image Assistant tool in silent mode. However, the process fails even before the analysis and installation parts.

The command I run is:

HPImageAssistant.exe /Operation:Analyze /Action:Install /Selection:All /Silent /ReportFolder:C:\HPIA\Logs /SoftpaqDownloadFolder:C:\HPIA\Drivers

For troubleshooting, I have downloaded and tested HPIA from both:

https://ftp.ext.hp.com/pub/caps-softpaq/cmit/HPIA.html

https://printerdrivers.com/hp-image-assistant/

The behavior matches exactly for both downloads.

The script says it is waiting for HPImageAssistant.exe, but then it just times out and quits.

Error:

Timed out waiting for:
C:\SWSetup\sp158107\HPImageAssistant.exe

Things I've already checked:

Running as administrator.

Antivirus is not blocking the process.

Download appears to complete successfully.

HP device is supported by HPIA.

Tested multiple machines with the same result.

So far I have considered:

The SoftPaq extraction is failing.

The extraction path was changed.

UAC is interfering with the process.

The script is checking the wrong folder.

Has anyone seen this HPIA timeout problem before? What was the cause and how did you fix it?

Thank you.
