WinDbg fails to start #18

windbg_fatal

I have a full procdump if you guys need it, Andy mentioned it might be due to an incompatible dll being injected.

I've tried to load the executable DbgX.Shell.exe using WinDbg but it's obviously checking the parent == explorer because I can't load it (in my user context) in windbg, it tells me access denied. Otherwise I would have loaded it and set a breakpoint on the error and given you more information..........

Let me know if you need more information chaps.

I attached WinDbg to WinDbg.Next (post crash) and here's the list of loaded modules, obviously you wont see the culprit if it's load fails causing the crash:

That error makes it look like a file is missing from the installation, although that would be very strange. Can you capture a procmon log from when this error hits? You can email it to windbgfb@microsoft.com if you don't want to post it here.

crispinwright commented 5 years ago

Yeah that was the first thing I checked Tim, the file is there: image

When I copy that folder to another location and run the exe, windbg runs fine (and is useable as well, it's not just a "UI load" that is fragile underneath if that makes sense).

I think the missing file error is a red herring, I just can't find a way to run windbg.next via windbg.old (if that makes sense) if I could do that I could see the stack and tell you whats going on....I'll do a procmon now with a filter for "DbgX.Shell.exe" (let me know if you want one without a filter as well) and i'll flick it to you.

I've had a look at the dump I shared with you - without symbols it's not fun, but none of the threads are showing an exception when I !CLRStack which is interesting - I would have expected (kind of) to see that, at least I can see the stack though on the MainUI Thread, and that looks like this:

So it looks like a couple of exceptions are happening, one seems to sort of get handled and then the second one doesn't and it's all over.

I just installed WinDbg Preview today. It started fine when running as a normal user. Then when I tried to run it as administrator (to try out time travel debugging) I get the same error, albeit a different dialog than attached above

The problem turned out to be that you have to originally install WinDbg Preview using an account that has admin privileges, not as a normal user. Then you can start it with admin rights.

Just posting this comment in case someone else is having the same issue.

Thanks, that worked for me! Had to install it as both an admin and as a normal user. I was then able to "run as admin" while logged in to a normal user account
