Rich Healey added the comment: I have an apology to make for wasting your time. Further investigation demonstrates that it was evidently fiddling with the Application Verifier that broke everything (although I installed it during my debugging attempts- I'm guessing that something else in VS h

Rich Healey added the comment: I've done some more fiddling with the debugger, once I discovered the Windows symbol servers, and a tool called application verifier some things started to fall into place. LuaPriv takes care of user privelidges, the program runs fine when I run it as administr

Martin v. Löwis added the comment: By "exactly the same problem", do you mean that your installation also runs into a break instruction in ntdll!CsrSetPriorityClass+0x40? Can you please also attach the debugger log (unless it's byte-for-byte identical with the one from richo)? -- _
