First Error

For the first error:

Process with an ID #### is not running.

The following steps worked for me:

- Close all instances of Visual Studio.

- Rename the IISExpress folder (in my PC is in C:\Users\jmelosegui\Documents).

- Add the *_CSRUN_DISABLE_WORKAROUNDS* Environment System variable with the value of 1.

Second Error

The following steps worked for me:

- Locate IIS 8.0 Express.

- Right click on it then click Repair.
