I built dprofiler from source using MSVC 2015, but everytime I try to attach to a process, it crashes.
Profiling by launching works though.

xwlan commented

you can run as admin to have a test, profiler require admin to attach to other process.

When I run it as admin it also crashes when I try to attach!
