Get the ISO file of VS2008 from Microsoft's website
Use WinRAR to extract the ISO file (ex. D:\VS2008), or copy the contents using Virtual CloneDrive to the hard drive.
Go to D:\VS2008\Setup.
Open file "setup.sdb" using Notepad.exe
Find the line [Product Key]
Replace the default key with your key (removing all the dashes)
Save the file and close notepad.
