I installed Visual Studio Pro 2005 from my MSDN CD's.  About 3/4 of the way
through disk two, I got the following error:

Error 1911.Could not register type library for file C:\Program Files\Visual
Studio 8\Common7\IDE\vsmacros.dll

I tried 'retry' a couple of times, then 'ignore'.  Setup went a little
further and then another error:

Error 1911.Could not register type library for file C:\Program Files\Visual
Studio 8\VC\vcpackages\VCProjectEngine.dll

Again, I hit 'retry' a couple of times, then 'ignore'.  Setup went a little
further and then got more errors, different filenames.  I thought that maybe
I had a bad CD, so I eventually hit 'abort'.  Setup then seemed to hang up
and not respond, so it didn't finish the rollback/uninstall.  I looked in
'add/remove programs' but it didn't show up, so I deleted the files in the
install directory manually.

Then I downloaded the DVD .iso version from my MSDN subscription area,
mounted the .iso and tried it again.  Same errors in the same spots.  This
time I just hit 'ignore' every time and let it finish the installation.  VS
will load, but any type of error during an installation, especially one where
I have to skip files, concerns me.  I also installed the MSDN Library off the
same mounted iso and also got a couple of 'could not read file' errors, but I
hit retry and and it completed installation.

This is on a Windows XP Pro 2003 machine that is a pretty new and clean
installation, in fact there isn't much else installed on this machine yet.  
It has plenty of RAM.  C Drive is running a little short on drive space,
right around 2GB free, but there is plenty of space on another drive, which
is where I was installing it to.

Any idea what would cause this or how I can fix it?  I really need to get
started working on this machine.  Any help will be appreciated.
