"Cannot run program" error with Web, Web Services apps.

I built small C# Web and Web Service applications in a
training class last week. The applications worked in the
class, but when I tried to run them again over the
weekend, they both bombed. Instead of getting my Web
page, or the Web Service page, I get a page full of error
text (below).

I am hoping the anwser will be obvious to someone.

I've tried a few things to address the problem, including
adding an "impersonator" identity to machine.config, and
web.config, and trying to figure out how the
PublicKeyToken works. Neither has led to success.

Thanks for any suggestions.

re: "Cannot run program" error with Web, Web Services apps.

Did you created the virtual directory as an application?
