Hi, I read some other topics related to a similar issue but not quite the same, so I'm posting this.
I'm trying to install Pulse Secure Client on a new PC. In the link on my business client's server I get the PulseSecureAppLauncher.msi file which I downloaded on my computer and executed it and got confirmation that installation completed successfully.
But then, when clicking on the server's provided web link to launch the app, it says "The server configuration requires the application to be pre-installed" and a subsequent message says "Detected an internal error. Please, retry. If the issue persists, contact your administrator".
In Control Panel I see the following installed:
Pulse Secure Setup Client
Pulse Secure Setup Client 64-bit Activex Control
Pulse Secure Setup Client Activex Control
If I rerun the app launcher for a new install it says it's already installed.
I went to delete the files and retried the procedure but I still get the same messages.
Before going through the client's internal helpdesk, which is quite slow and cumbersome, I'd like to have some suggestions of what might be the cause. I'm stuck in a loop and can't work!
Pulse Secure Application Laucher is not the Pulse Secure Client.
Pulse Secure Application Laucher (aka PSAL) is just a small application which is used (at least) by the browsers to launch the several applications of Pulse Secure.
Pulse Secure Client it self, depending of the configurations of your company, could be installed via browser using VPN URL, but it need to have Pulse Secure Laucher before.
You should contact your company to check which is the correct procedure to installl and configure Pulse Secure Client.
