Issues with Safeguard Privilege Managemer for Windows

We've had this product for several years, lately I've been having issues with client installation, and when the client installs, Instant Elevation requests do not work. For client install, I can see that the GPO applies just fine to the target system, however, no signs of the client, Valdation Logic on the GPO's are targetting the systems just fine but I am not sure what is going on, is there a log where I can see why client is not installing and Instant Elevation requests are not working?

I am running 

One Identity Safeguare Privilege Manager for Windows  4.7.0.31, running on Windows Server 2019 Standard.

thanks
