Answer 1

I've been experiencing the same issue on Win7 SP1. Web app compiled targeting .net 4.5.2 and running on .net 4.6. And I haven't been messing with the useLegacyJit or useRyuJIT registry flags.

Turned out "Enable 32-Bit applications" was unnecessarily set to Enabled on my app domain. Disabling it fixed the problem.
