On upgrading from 9.1R14 to 9.1R15.2, people with Pulse Secure Setup Client 9.1R14 can not access anymore. They have to manually uninstall that program in order to update it.
No, I have just upgraded to 9.1R15.2. I have not try 9.1R16 version yet. Our service provider recommended to upgrade to 9.1R15.2.
Besides, I asked our service provider a few days ago to open a support case but he has not confirmed yet whether he did it.
I wonder we are not the only one who is suffering this bug.
There is an open case: 00520556
Unfortunately, our reseller has not arrange yet a remote session to troubleshoot the issue. I work for the end customer and I am in charge of the VPN SSL service.
