Installing Orcas Beta 1 from the 5.32 GB ISO Image

Conventional single-layer DVD-R/RW and DVD+R/RW discs hold 4.7 GB. So unless you have a double-layer DVD burner and media, you won't be able to run the 5.32-GB Visual Studio Orcas Beta1 Setup program from a physical DVD.
Setup fails before completion of .NET Fx 3.5 when run from a networked drive. Believe Setup's Start Page where it says:
Some components require that network connections be temporarily suspended during setup.

If you try installing from a network drive, which includes third-party apps that mount ISO images to virtual CD or DVD drives, you might experience what appears to be a non-fatal timeout message while Setup is copying its initial set of files. Even if not, you'll undoubtedly see this message during the installation of .NET Fx 3.5:

and end up with this screen when installation fails:

This means that your double-layer DVD burner must be local to the machine on which you want to install Beta 1. Virtual machines connect to the host OS's physical drives as networked drives, so you're out of luck if you want to install Orcas Beta 1 on Vista as a guest OS.

The Solution

Use Daemon Tools' free Virtual Daemon Manager (VDM) to mount the en_visual_studio_orcas_beta_1_professional_dvd_23591.iso image file to a virtual DVD drive. The current VDM version (4.09) works fine under Windows Vista as a host or guest OS, despite what you might have heard on the Web.

Note: When you install VDM on virtualized Vista, save and run the setup file. You must reboot to finish VDM's installation. Under Virtual Server 2005 R2 RC1 with Vista as the guest OS, you must explicitly run daemon4091-x86.exe a second time to complete the installation after rebooting.

Update: 4/24/2007: Commenters have suggested using WinRAR or IsoBuster to extract the image to executable files. WinRAR isn't free (it has a 40-day trial license) and IsoBuster requires the PRO version ($29.95 personal, $49.95 professional) to open an image of this size. Some commenters have suggested other virtual DVD drive apps, but VDM is free and has proven itself under Vista.

why not just copy the files from the ISO to your local HD and install from there ? (i.e. extract the ISO with WinRar for example)

I like to use VCdControlTool.exe since you don't have to extract 5GB+ of data for no reason, you just mount the iso as a CD ROM drive. You can download VCdControlTool.exe from Microsoft here (
It works on XP but I don't know if it works with Vista

You can also use ISO-Buster or rename the file to .rar or .zip and extract with winrar

Virtual CloneDrive is free, and worked well for me on Vista.

Yup got this exact error, but I extracted all files to a local drive so apparently it's not the ISO manager that's the problem in this case.

Why the Team System version of Orcas is only 1.5G ?

Dumb question time...

Can anyone tell me if the SQL Server free products like Management Studio Express can be run off MS Virtual PC for Mac?

And how about Cisco VPN?
