This will all be part of the beta. I don't have any specific instructions for you at this time; we'll be looking at this in a week or two once the SI5.5 update is re-released.
I believe 64 bit is still in beta... but I can tell you it works!!! I've been waiting for an official release / news briefing - but haven't seen it yet... but last I heard was "any day" and that was 3 weeks ago.
How does one get ahold of this beta? I would very much like to try it out.
If I cant get it, what is the ETA for the 64bit version?
This has been available for sometime now (no longer BETA). Please email support (support at d-tools.com) with your request and it will be sent out to you. All of the new install CD's also come with 64/32 bit version.
