I had Pulse Secure installed and working on this server, but suddenlly one day it stopt working (it began to restart continuosly). So I uninstalled it and when I tried to reinstall it I got the error: "Module C:\Program Files (x86)\Common Files\Pulse Secure\8021xAccessMethod\JNPRTtlsProvider.dll failed to register. HRESULT -2147024770". I found the post when they recommend to install the Wireless LAN Service on the server and did so and now I'm getting the error: "Module C:\Program Files (x86)\Common Files\Pulse Secure\JUNS\PulseSecureServicePS64.dll failed to register. HRESULT -2147024770". It's a different .ddl file.
Is there a different solution for that?
@djgonzal Wireless LAN service installation should be fix this issue. If not, please do a deep clean by deleting all files, folders, registry keys related to Pulse Secure/Juniper Networks, reboot the server and attempt to install the Pulse client again.
