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.

- Start Visual Studio in administrator mode. (In *Windows*, right click the executable file and select *Run as administrator*).

Second Error

The second error:

The following steps worked for me:

- Go to Control Panel.

- Select Add/Remove Programs.

- Locate IIS 8.0 Express.

- Right click on it then click Repair.

- Your certificate should be back!
