--- Comment #5 from Charles Davis cdavis5x@gmail.com 2013-09-02 21:14:39 CDT --- I can't see anything obviously wrong from your log. My patch maybe got you a bit further (the attempt to import the certificate no longer fails), but one of the CryptVerifySignature calls that the launcher is making is still failing.
One odd thing I've noticed about your log (vs mine) is that the launcher, after verifying its code signature, makes at least three additional CryptVerifySignature calls (it might make more, if one of them weren't failing) that it's not making on my system for some reason. (There are, in fact, hundreds of CryptVerifySignature calls in your log, but most of them seem to be coming from Wine, since most of the calls are directly to the wide version, but the launcher prefers to GetProcAddress the ANSI version and call that. They must be partying like it's Windows 95 over at CIG. :) Another thing--and this is likely related to you having this file--is that the first VerifySignature call triggers Wine importing a bunch of CAs from "/etc/ssl/certs/ca-certificates.crt".
Hmm... Do you have a root CA named 'UTN-USERFirst-Object' installed? (You might find it under the filename 'UTN_USERFirst_Object_Root_CA.crt'.) I do, and apparently, it's needed to verify the intermediate CA ('COMODO Code Signing CA 2') against which the launcher was signed. If you do, or if you don't and installing it doesn't help, you might also find it helpful to install that intermediate CA.
