I posted this question and have a freshly minted code signing cert from Thawte.

I followed the instructions (or so I thought) and the code signing claims to be done right, however when I try to verify the tool shows an error.

I have no idea what it means and no idea how to fix this. Any comments would be appreciated.

Command line to sign exe:

signtool sign /f mdt.pfx /p password /t http://timestamp.verisign.com/scripts/timstamp.dll test.exe

Results:

The following certificate was selected:

Now, when I try to verify imagine my surprise:

signtool verify /v test.exe

results in:
