Werner SQLite driver works only on 32-bit windows version. It just doesn't have compiled binary dll for 64-bit version.
I'm afraid there is nothing I can do with it

You may try to use 32-bit version of DBeaver - thus it will load Werner driver correctly. You will need to setup 32-bit Java 1.6 or later on your 64-bit Windows. I understand that it is not an easy workaround but I can't figure out any better solution at the moment..
Thanks
