<p>I am getting the following error when trying to install Visual Studio 2005 on my 64bit, Vista computer:</p>

<blockquote>
  <p>"1305.Error reading from file
  C:\Program Files (x86)\Microsoft
  Visual Studio 8\Microsoft Visual
  Studio 2005 Standard Edition -
  ENU\SITSetup.dll"</p>
</blockquote>

<p>I have successfully used the same DVD's to install Visual Studio on my old XP machine, and I can find the file (SITSetup.dll) on the DVD...and copy it off...so I don't think this is a case of having a bad DVD. At the time the error message pops up, I can see the file on my hard-drive, but it has a 0 size.</p>

<p>I've Googled this problem, and found some ideas, but nothing has worked thus far. Any suggestions would be appreciated.</p>

I just installed it yesterday on my Vista box (32-bit, which may be the problem). It seemed to go through fine so I don't know what to tell you other than than when I first launched the app it notified me of "known compatibility issues" and recommended that I install both the SP1 and Vista SP! updates. No further issues past that.
As such, I would suspect either a problem with the 64 bit OS (though
Microsoft says it's fine...
) or other software on your machine. If you have a virus scanner running, for instance, disable it while installing.
