Can't insert admin credentials on remote computer

[Murat Germaner]

Hi,
Our company is running 16 individual laptops with Windows 8.1 and Windows 10 OS at 16 outlets.
The laptops are operated by the salespeople as standard users without administrative rights.
I often connect to these laptops remotely with TeamViewer 7.
When I want to install software or add a printer etc. UAC window pops up and requests administrative credentials. However, although some laptops let me insert the admin password and allow me to take the action with admin rights, other laptops freeze the UAC window as soon as I try and put in the first digit and I cannot install any applications etc.
I believe it is a setting that must be switched on to allow the administrative password input remotely but I couldn't find it. Otherwise remote access on a computer running with standard user rights becomes pointless.

I would appreciate your help.

I think the difference is under what user teamviewer was installed

If Teamviewer is installed as a local user, you can't then get admin access
