Localhost shows 404 - web server loads fine. Help please.

I cannot load the fckeditor on my development box, but it works fine on a web server.

Are there any known issues with iis7 windows XP? (asp.net /vb.net)

I have been searching for a solution for 2 days, but could not find anything relevant.

On my computer (localhost/appname/) I get a 404 page not found error.

I looked at the log files and only 404 references “/fckeditor/editor/fckeditor.html”

Here’s the full line:
2009-10-20 03:10:56 ::1 GET /fckeditor/editor/fckeditor.html InstanceName=ctl00_ContentPlaceHolder1_txtDescription&Toolbar=Default 80 - ::1 Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+6.1;+Trident/4.0;+SLCC2;+.NET+CLR+2.0.50727;+.NET+CLR+3.5.30729;+.NET+CLR+3.0.30729;+Media+Center+PC+6.0;+InfoPath.2) 404 0 2 8

Any help would be appreciated.

Thank you in advance.
