Have a warning message/popup when the upgrade/Update/Cumulative Update/Fix pack if the current user is not the same from the last execution
We can lost lot of time if we execute the upgrade, Update, Cumulative Update or Fix pack with a "simple" user account.
Could you add a warning message like this:
'Warning: you are connected as "Bob", the last time a K2 setup has been executed, you used the account "K2Service"'
In the same time, you can check if the execution has been done with the right click "Run as administrator" with a corresponding warning:
'Warning: you didn't execute this setup with "Run as administrator"'
