[SOLVED] iVentoy 1.0.36 - Auto Install Script (autounattend.xml) stopped working - matmus06 - 06-29-2026

Hello,
After updating to iVentoy 1.0.36, the Auto Install Script feature no longer works.
What worked before:
  • iVentoy 1.0.35 → everything works perfectly
  • Same Windows 11 25H2 ISO
  • Same autounattend.xml file
Problem with 1.0.36:
  • The script is correctly added to the ISO in the web GUI
  • It is set as Default Auto Script
  • I tested with multiple different XML files (including minimal ones)
  • Tried with and without Auto Script Select Timeout
  • File is named autounattend.xml (UTF-8)
Despite all that, Windows Setup ignores the unattended file and runs in normal (manual) mode.
Environment:
  • Windows 11 25H2 ISO
  • iVentoy 1.0.36 (latest version)
  • Server running on Linux Debian 13
Tests done:
  • Downgrading to 1.0.35 immediately fixes the issue
  • Removed and re-added the script multiple times
  • Tried renaming to unattend.xml
  • Restarted the iVentoy service after every change
Is anyone else experiencing this issue with version 1.0.36?
Is this a known regression or an intended change?
Thank you in advance!

Thank you,
I tested the RC version and Auto Install Script works again with my Windows 11 25H2 + autounattend.xml.
The issue is fixed in this RC.
I am currently using the Pro version. Will this fix be included in the next Pro release soon?
Best regards,
