Am currently testing on the latest Windows 10 Preview Build (build 10240, which some have claimed is RTM) with PCS OS 8.1R4 (build 37085) but I am unable to get Host Checker to launch. I'm using Internet Explorer 11, not Edge. The JuniperSetupClientControl appears to install OK but Host Checker isn't launching - it just sits at the Loading Components screen.
Tried the previous fix of adding our domain to the Compatibility View list but to no avail.
It used to work with previous Preview builds but it seems this latest one broke something.
I am able to replicate similar behavior with Windows 10 preview build 10240. I was able to workaround this issue by disabling Protected Mode on IE or adding the SA url to the Trusted Sites zone. We will further investigate if there is anything we can do to help prevent this issue.
In addition to what kita referenced, is this a new install or upgrade from an older PCS OS connection? If the latter, does a fresh install after removing any Juniper Networks/Pulse Secure setup client components pass?
