3. Install C# Express SP1 (note depending on what you have installed this may take a long time)
4. Run C# express
5. (If you are using Vista) then install Visual Studio SP1 for Vista and run C# express

All downloads should come from the official Microsoft site - be very wary of any sites claiming to have mirrors.

Troublehooting:

• There are always a few reports of bad installs possibly caused by downloading errors especially on slow connections. Try using a different browser, clearing your internet cache or using a download manager
• Try running the MSI installers with the logging option and looking in the log for errors. If you want to post a log to the forums PLEASE use a pastebin as they are huge and your post will likely be deleted.
• Package Load Failure
• Trouble installing C# Express including speeding up install time - see Scott Guthrie tips and Heath Stewart tips
