1. I keep trying to install the addon studio, but I keep getting the following:

    "Microsoft Visual Studio Shell Isolated Edition

    Cannot find one or more components. Please reinstall Addon Studio for World of Warcraft."

    Is this a know issue and is there a workaround.

    You'll need to report this issue on codeplex, we don't support the addon studio software here.

    Thanks,

    I checked and I found the problem to be I needed all of the updates for SDK1.
