Are you saying that you are installing our Harmony Endpoint Client and they also trying to install Harmony Web Protection Browser Extension as well?
If so, the Harmony Web Protection Browser Extension is now part of and has been part the Harmony Endpoint client for some time now via the SBA/Threat Prevention Blades. AFAIK you cannot install them both separately side-by-side. If you already have the Harmony Endpoint client installed you should just be installing it as part of the SBA/Threat Prevention Blades.
If you are not talking about our Harmony Web Protection Browser Extension, are you just saying that GPO Policy settings for Internet Browser themselves are not applying with our Harmony Endpoint client installed?
