Visual Studio 2005 Beta 1 Installation -- Round 3

I'm still wrestling with installation of VS.NET'd the package, still having the same issues.  I'm not the only one running into problems (he had the exact same issues, and I'm having the same issues as this commenter after following the steps outlined in the post).  It's baffling as I had no issues with any of the pre-betas whatsoever.  I'm about to relegate this to the trash bin and give up; if anyone has successfully installed beta 1, let me know.  Cheers.
