Answer 2

Check that the user its failing has a IISExpress\config folder in their home folder. If not then copy it over from the user where IISExpress is working. This is a common fault when the config files/folders are missing.

1. try as everybody do

   1.1. Delete all files in C:\{users}\My Documents\IIS Express\config

2. If it still not work, try this below

   2.1. Delete all files in {your project}\.vs\{your project}\config
   (Note: .vs\ folder is hidden make sure you show hidden folder first)

   2.3. Select "Web" Tab > in Project URL > change your port (Example: change from http://localhost:1096/ to http://localhost:1097/)

   2.4. Save and run your Project again.

Answer 4

To clarify John's comment - the directory will be something like C:\users\jmitchell\My Documents\IISExpress\config. I assume John is correct in that if it doesn't exist you would need to create the directory.

Alternatively the directory could already exist and just be corrupted. This is what I believe happened in my case. I had previously installed WebMatrix but ran into all sorts of issues today. After uninstalling IIS Express, Web Platform Installer, WebMatrix, and some SQL Server Management Objects, and then reinstalling WPI & WebMatrix, I came across this post.

I actually got IIS Express to run successfully after deleting the config directory mentioned above, and then re-running C:\Program Files (x86)\IIS Express>iisexpress.exe /trace:error

And I ONLY wasted two hours of my day on this! Thanks Microsoft!

Answer 5

I got this problem after upgrading to Web Platform Installer 5.

The quick fix for me was to also upgrade to Webmatrix 3 (http://www.microsoft.com/web/webmatrix/)

using rider i had to remove this config file found here and that worked \.idea\config\applicationhost.config
