Failed to load .NET framework

Solidworks is failing to start on my machine with the error "Failed to load .NET framework". Has anyone had this issue and overcome it? This is a new install. I have never successfully gotten Solidworks to run on this machine.


I have tried both SW 2018 SP 0.1 and SW 2017 SP5, and I get the same error on both versions. I'm not having any issues with .NET for any other applications. On some of the failures, but not all, I am seeing the following Windows Event:

".NET Runtime version 4.0.30319.0 - There was a failure initializing profiling API attach infrastructure.  This process will not allow a profiler to attach.  HRESULT: 0x80004005.  Process ID (decimal): 15436.  Message ID: [0x2509]."
