Deadline 8 Slave crashing on start up

I have installed deadline 8.0.0.69 on all of the windows machines on our farm. All of them are working happily except for one. The only thing that is different about this machine is that it is running a Xeon E5530 as apposed to an i7. When I try to lunch the slave with the UI or as a service, it instantly crashes. I know that it is communicating with the repository for a moment because it shows up in deadline monitor. I have tried installing it in safe mode with all firewalls and anti-virus disabled. I have tried both deadline 8.0.0.69 and deadline 8.0.1.0 both crash in the same way. Any ideas? Let me know if I can proved any other helpful info. Here is the log:

I should also note that this node worked perfectly fine running deadline 7.

It looks like it’s dying in the Python Sandbox communication code which is a new feature in 8. I’ll ask around tomorrow on the Core side and see if anyone has any insights (it’s holiday today in Canada).

Any insights?

I had the same thing, had to manually install the latest .net framework on the machine:

I took your advice and reinstalled .NET 4.6.1. It is now working fine, thank you.
