When using Support Automation and establish a session with an end user, when the analyst tries to take control and select to open or run a program with administrator credentials the screen seems to be hang, but the end user is seeing the credentials request.
The issue was caused by having the User Access Control (UAC) of the OS at the highest level, this configuration request for credentials every time there is a modification to a file or an external user requires administrator permissions, this will not allow or it will prevent the analyst to view the credentials window during the web session.
In order for the analyst to be able to take control and run programs that require administrator permissions, it is necessary to reduce the UAC to the minimum level, it will be necessary to restart the OS and start over the Support Automation session again.
In order to turn off UAC:
1. Go to Control Panel > User Accounts and Family Safety > User Accounts > Change User Account Contro
2. Move the slider to the bottom: Never Notify > OK > Restart machine for changes to take effect
3. Start over the Support Automation session again
