(In reply to comment #11) Whats the status on both issues?
I'm not even sure the patch is correct anymore. I tried writing some tests based on the patch, to see if Windows actually behaves this way, but AFAICT, it doesn't. Also, the issue seems to be gone with recent versions of the SC Hangar Module installer, though I haven't tried it in awhile. I'll have to try the ESO installer sometime. (Somebody contacted me off-list and told me it works on Windows 7, but not on Wine, with similar symptoms as the SC installer. They were even helpful enough to attach the certificate data that Wine doesn't like.)
As for the Debian issue, it looks like what they want to do is change the package layout to better accommodate code-signing CAs like the USERTrust CA used to sign these two games' installers: ca-certificates Git has separate *.pem files for SSL/TLS, email, and code signing. They're leery about adding it directly, because it's not trusted for either SSL/TLS servers or signing emails (just signing binaries). (At least, that's the explanation I got.)
