New Install VS 2010 - Cannot Run Basic Web Application in Debug Mode

Question

I recently installed VS 2010 and created a simple Web Application (WebApplication1) and tried to run it in Debug mode and received the following error:

"Unable to start program http://localhost:4177/Default.aspx"

I then set the properties to Use Local IIS and now receive this error:

"Unable to start program http://localhost/WebApplication1/Default.aspx"

I have VS2005 installed on the same PC and have been using it for many years.

OS: Windows XP SP4

Hi Ray,

Thank you for posting in the MSDN forum.

1. Open the IE web browser, Tools->Internet Options->Security->Local intranet ,"security level for this zone: all", and put the security level to low. Check it again.
2. Tools->Internet Options->Security->Trusted sites, add localhost as a trusted site.
   Make sure protected mode checkbox is unchecked. Check it.

Reference:

Unable to start program element not found.

Best Regards,
