-------------------------+--------------------------
 When I launch Tor Browser 4.5 for Windows with EMET 5.2 configured for all
 mitigations (except ASR), Tor Browser crashes.

 I've tested so far on Windows 7 Pro and Windows 8.1 Pro (both 64-bit), and
 Tor Browser 4.5 crash on launch with EMET (version 5.2, the most recent
 version) notification "SimExecFlow" (ROP Simulate Execution Flow). I
 tested both the initial launch and the subsequent launch (in case it was
 specific to the initial Tor Browser setup), and both crash with the same
 SimExecFlow notification from EMET.

 When I disable SimExecFlow in EMET, Tor Browser launches fine.
