Description

When the dbgeng.dll cannot be loaded, it is often times that the dbgeng/dbgcore/dbgmodel/dbghelp.dll is already loaded from a different place (usually systen32) which is incompatible with the one binja wants to use. We should detect such failure and give users better explanation.

We should also look for a better way to fix this so that the users would not be bothered in the first place
