JRiver 27 seg faults in Gear Isolation

[Primare11]

I have been using Snakeoil 1.1 with JRiver 25 as music server since 2019 with great result, it plays great and no problems whatsoever.  
Now when version 1.2 has been released I decided to try it out, in Vmware, it's much easier to install with the new script on top on Ubuntu server.
However I can't get Jriver 27 to start, I also have some dependency problems during install but I sort them out:

I'm using a remote KVM to work around this. Been meaning to write a blog about this, but still waiting for other misc parts to arrive before I can do it. PiKVM allows me to load a ISO remotely and boot up a remote computer. It's really flexibile.

I suspect running a VM could be the issue for the fault. Make sure:
1. You are giving your virtual machine enough virtual memory
2. JRiver might be using some CPU extensions that is not enabled in your VM By default. Shut down your VM, go to settings, under Processor, enable all options (or one by one) and see if it works. Alternatively check what extensions JRiver needs and see if you can pass it through somehow. Proxmox gives me more flexibility to do this, unsure if VMWare Workstations do the same.

Thanks for the prompt replay.
I have the following settings in Vmware Workstation 

• Memory = 4 GB
  
• Processors = 2
  •  Options:
    •  Virtualize Intel VT-x/EPT or AMD-V/RVI
      
    •  Virtualize CPU performance counters
      
    •  Virtualize IOMMU (IO memory management unit)
      

I tried to disable/enable these, still the same error:
   [Mon Jun 28 15:35:03 2021] mediacenter27[1346]: segfault at 10 ip 000055d1bff03070 sp 00007ffcc854d380 error 4 in mediacenter27[55d1befa7000+1241000]

However, I install Ubuntu 20.04 Mini (Desktop install where you select "mini" during the installation), with the exact same VMWare settings, and there Jriver starts up.

I also notice one thing, have you changed the windows manager to IceVM since Snakeiol 1.1, wasn't another windows manager used then?
If yes, can that be the problem?

II did an search on Jriver and segfault and found this: https://yabb.jriver.com/interact/index.p...#msg707248
It's quite old, but they talk about a display driver, has that been updated in Snakeoil 1.2?

I will try to test some more during the week.
