Orca MSI Install Failure; Trusted Root Certificate Error

Problem

You've edited the Automox MSI with Orca to embed the access key, but installation fails with:

• failed to add root cert
• PostInstall_TrustedRootCert: failed to configure trusted root certificate
• No executable found at C:\Program Files (x86)\Automox\amagent.exe
• Current Agent service status is STOPPED
• Installation result reported to IRS: False

Despite these errors, the installer reports: Configuration succeeded!

Root Cause

Using File → Save As in Orca strips embedded binary data (including the trusted root certificate) from the MSI. The Configuration succeeded! message only reflects the MSI table configuration step, not the full post-install actions.

Resolution

1. Clean up the failed install
Run the CleanUp-AxAgent PowerShell script as Administrator (found in the Cannot Uninstall Automox Agent KB article), then reboot.

2. Re-create the MSI correctly
Download a fresh installer from the Automox console, open it in Orca, add the ACCESSKEY property, then save with File → Save — not Save As. If Save As must be used, first enable "Copy Embedded Streams During Save As" under Tools → Options → Database.

3. Reinstall
Run the corrected MSI — the agent should install cleanly with amagent.exe present and the service running.

Additional Check

If amagent.exe is still not found, check that these registry values point to C:\Program Files (x86) and not an alternate drive:

• HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\ProgramFilesDir (x86)
• HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\ProgramFilesDir
