Net V2 Runtime
This post's technique may or may not work, but it could be worth testing in this type of scenario. By checking RuntimePolicyHelper.LegacyV2RuntimeEnabledSuccessfully at runtime, I can decide whether to enable the native solver, and only do so if I successfully bound this policy. And therefore, I still need old versions of .net installed? share|improve this answer answered Sep 18 '13 at 14:32 Oliver Kane 421218 add a comment| Not the answer you're looking for?
