I do not have the files*. Try either MS tools or right click on the
.exe to see it's properties. There should be some mention if it was
signed with authenticode.


* if you're running on on 64bits Windows then it could be a change for
the new PE format (that Mono might not support, never had a bug report
for this but it's a possibility).
