SignTool error: SignerSign() failed." (-2147024885/0x8007000b) when signing msi file

Question

We recently purchased an EV Code Signing Certificate. I followed instructions and I can successfully sign our built applications (exe files), our libraries (dll). However, I can't sign our setup packages (MSI files), I always get this error:

SignTool Error: An unexpected internal error has occurred. Error information: "Error: SignerSign() failed." (-2147024885/0x8007000b)

I don't see anything in Event Viewer. I am really stuck here, I don't not understand how same command could work for certain file types and not for msi files.

Thanks in advance for your help!

Answer 1

Check the log for more info:

1. Run Event Viewer app.
2. Open the event log: Event Viewer (Local) > Applications and Services Logs > Microsoft > Windows > AppxPackagingOM > Microsoft-Windows-AppxPackaging/Operational
3. Look for the most recent error event

In my case I had a mismatch in publisher string in Certificate and Manifest.
