You may want to run a checksum of your 2.0RC2 image. I’ve seen some reports that some of the download sites (one in Switzerland?) may have bad copies. Incidentally, my 2.0RC2 CD ISO has this SHA-1 hash: f7abb94f0808b9675d7f072fb662c3256b051e0e and has been working.
🙂 And how do you think I figured that? 😆
BTW, Switzreland mirror has a good copy. Just don’t use download managers.
