ERROR - A required privilege is not held by the client

Hi Esad,

I am sorry to know you are having troubles with adding code in your project and will assist you to sort this out. 

This type of error is related to the level of permissions your user has on the machine. I guess that you are either not an administrator or the User Account Control is set to a level, which prevents the user to apply certain changes on the computer. 

Here is what you can try to fix this:

1. Start Test Studio with Admin rights explicitly. Then check if you can compile the project successfully.
2. If this is still not helping, turn off the UAC - set it to 'Never Notify', this is one of the Test Studio system requirements. This modification requires restart of the machine to take effect.
   You can check if the change persists after the restart, as this depends on the user permissions granted for your user. 
3. Once the UAC is set to 'Never Notify', try to compile the project again and check what is the outcome.

Please, let me know if you need any further assistance on the case.

Regards,
Elena
