How would I click on details through wine? Mind elaborating on that, I have no idea what you are doing or how to reproduce it.
If you use Wine Explorer to double click the cer file, you should see a prompt similar to the screenshot from comment #3.
I get an "The certificate is issued by an unknown or untrusted publisher" warning. Is that what you mean?
Yes, that's what I mean. The root certificate is present on the system, but Wine thinks it is invalid.
