mIRC 7.19 crashes when connecting to any server with ssl. I'm using Windows 7. Is there an official location to download older versions so I may revert back until this is fixed?

Do you have the latest version of OpenSSL installed? Try installing the latest version to see if it fixes your problem:

If not, you should be able to download the previous version (7.17) here:

By the way, I'm running mIRC 7.19 with Windows 7 x64 right now and it's working fine.

Upgrading the dlls solved the problem, thank you.

Do you happen to know what version you had installed?

I'm not sure which, also I'm nearly positive I had downloaded them from this site, or one it linked to in the past.

Edit: I had these on a separate installation of Windows. They worked with previous versions of mIRC but not the current. I am unsure of how to identify them. Here's a link: http://www.megaupload.com/?d=N6B3QP9Z

Looks like "0.9.6b 9 Jul 2001"

Thank you. Upgrading Open SSL fixed the 7.19 crash issue.
As does re-installing 7.17 which is/was the version I upgraded from. Win XP Sp3 32bit
