Hello,
When i try to install the Looking glass client on my guest Windows 8.1 it crashes the installer with the following error log:
|Problem Event Name:|APPCRASH|

Ive tried the Stable, RC and Bleeding Edge versions but the same error appears.
Is there a solution to this?

Sorry but Windows 8.1 is not a tested platform. It seems like the service code is bugged for it. I would suggest you don’t install the service and instead manually launch it (or use a scheduled task) as directly launching it doesn’t invoke the service routine.
The down side is that without the elevation to run a SYSTEM it can not make a few privileged win API calls to improve DXGI performance.

The same error also appears in the application itself even when i don’t install the service with it.

Ah ok, we can likely work around that one, I will see about pushing in a fix

This should be fixed in the latest bleeding edge, it should also work as a service too.

Sweet, thank you.
Seems to install just fine, i haven’t set up a connection with my host yet so i will report back when i’ve got it running.

Seems to work fine for a couple of seconds and then looking glass opens many of instances, the host application cannot connect to the guest at all.
it did kind of work before but only the host application would crash, should mention that the host is using the linux-libre kernel.
Tried installing the guest app without the service and it stopped launching a bunch of instances, but manually opening the program results in this error:

Did you set the virtual video device type to none in libvirt? (you must type this value). LG can not operate with the virtual device at the same time as it doesn’t support DXGI DD

So after redoing the installation LG works again for a couple of seconds and then exits the application

Firstly, I am surprised that nouveau is working at all, but even still the error is unrelated.
Can you please do a debug build and run it under a debugger, if you don’t know how to do this please see: https://www.youtube.com/watch?v=EqxxJK9Yo64

glFenceSync(GL_SYNC_GPU_COMMANDS_COMPLETE, 0); is the offending line in LG that triggered the crash, unfortunatly it has nothing to do with freeing memory. This means that this is a nouveau bug and there is nothing I can do about this.
