VS2010 error: Unable to start debugging on the web server

Question

I get error message \"Unable to start debugging on the web server\" in Visual Studio 2010. I clicked the Help button and followed the related suggestions without success.

Answer 1

Another thing to try (this is what worked for me):

In IIS, click Application Pools > (Your Site) > Advanced Settings, and change "Enable 32-Bit Applications" to True.
