firstly have you read this:

this may/may not help you in resolving the problem.

Secondly, have you tried to install it from another DVD drive? What about a different computer? Same problem?

Thirdly, have you been able to create an image of this media, using something like nero burning ROM for example, then mounting this using a Virtual CD tool and running setup from the harddisk?

"... problem has been encountered while loading the setup components visual studio"

(2) When setup.exe is run form the disk (or ISO disk) then the following message (eventually) appears:

(drive letter):\vs_setup.msi could not be opened

Possible Cause:

Installing Visual Studio Express over Visual Studio 8

Fix:

As described in previous post ie:

(1) Rename the Visual Studio directories to something else (ie. add REMOVE to the folder name)

(2) rename the following Register entry using REGEDIT (use with care!)

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0 (ie. change \8.0 to \8.0REMOVE)

(3) Download the Windows Install Clean Up utility at: http://support.microsoft.com/default.aspx/kb/290301

Use this software to 'clean up' anything with Visual Studio in the name.

(4) Reinstall the Visual Studio software

I've tried that but couldn't reinstall or uninstall VS 2005. Is there any other way?

I was having the same issue when trying to load a trail version of Vision Studio 05. This allowed me to get past the error message for the re-install but now it's saying I have a trail version already loaded and I need to uninstall it before I can reinstall it. However, when I try to uninstall it I'm getting the same error message "vs_setup.msi could not be found." So how do I uninstall the trail version so I can re-install it?

I had this same error but for a differnet reason. Basically I'd downloaded the image file to my local PC and I needed to install it to a server through terminal services. So I renamed the .img to a .iso and mounted it. I made my local drive resources available through terminal services and just tried to install VS2005 on the remote server through the relevant drive mapping and it would start the install and stop after about a minute with the error mentioned in the subject.

However I found that if I shared the mounted drive with standard windows filesharing and access it over the network via this standard network share (instead through terminal services local resource mapping) it allowed me to install everything without error.
