error message reads:
Unable to start debugging.
Cannot locate Windows Internet Explorer.
I tried different configurations. The error shows up on:
Vista Pro x64 SP1 or SP2
VS2010 Express or Ultimate
Silverlight 3 or 4
Multiple web browsers installed, but IE 8.0.6001.18975 is the default.
I have uninstalled and re-installed nearly everything, except the OS, Vista 64bit.
Clearing the Silverlight checkbox at ProjectWebSite > PropertiesPages > StartOptions > Debuggers allows me to debug (F5) the website in Internet Explorer, but I know the Silverlight debugger is not running now.
I checked this report of the same error,
My comment (BeeLabs) is currently the last with no reply. I dubt that I have the same problem because debugging ASP.NET without Silverlight debugger works fine. So it is not a issue of "locating" Internet Explorer.
I have marked this Error Report Feedback and a Blocking Issue. I assume this means the issue is stopping from doing something vs. a performance issue.
