Re: cisco nac agent for windows 8.1

Hi Ibrahim,

As per the compatibility matrix Cisco NAC Agent version on ISE 1.2 is supported for Windows 8 with IE 10. It means that you are on the supported version only.

For the agent not popping up , can you please check the below settings.

1)In Windows 8, Internet Explorer 10 has two modes: Desktop and Metro. In Metro mode, the ActiveX plugins are restricted. You cannot download the Cisco NAC Agent in Metro mode. You must switch to Desktop mode, ensure ActiveX controls are enabled, and then launch Internet Explorer to download the Cisco NAC Agent. (If users are still not able to download Cisco NAC agent, check and enable "compatibility mode.")

2)When you create a Cisco ISE client provisioning policy to accommodate Windows 8, you must specify the "Windows All" operating system option.

3)Windows 8 RT is not supported.

Re: cisco nac agent for windows 8.1


We face this problem and we use the new NAC agent which is 4.9.4 as I remember so you need to crete new client provisioning policy for windows 8.1 and the new NAC and compliance agent.

Also the ISE patch must be installed, try the latest patch which is 5.

Do you still face the error

Do you still face the error message appears on the NAC agent that the OS is not supported? If yes, then you need to know the exact version of your Windows 8/8.1 machines.

Can you please submit here a snip of the error message along with System Properties from the machine facing the problem?
