I see the following error whenever I try to debug "Cross Platform" under "C++" category: "Unable to start debugging. Unexpected GDB output from command "-target-select remote :5039". Remote connection closed"
I've installed all of the contents when I downloaded Visual Studio 2015 community and I ran it on Windows 10 Pro which supports Hyper-V.
I've been searching a solution for this and I've found an assumption:
"What is your debug target, the VS Android Emulator? When we saw this before it turned out to be a bad emulator image. Do you have this problem with all targets (e.g. if you try a physical device) or just one?"
In my case, I just tried this via Emulator(VS Emulator 5" Lolipop (5.0) XXHDP Phone (0x86 -...)
So I've sent an Email to VS 2015.
And the answer was like this:
"Sorry for the delay in responding we were looking at an emulator image of another user that ran into this problem so I was waiting until we had the results of that investigation to report back. We actually were not able to find anything wrong the emulator itself, our current hypothesis is that it is a network or adb problem interfering with GDB’s ability to connect to GDB server on the remote machine. Do you see this error every time you try to debug, or if you reboot the emulator will it work sometimes right after the reboot? Next time you see the error, can you open the emulator’s console mode by going go the Hyper-V manager and double clicking the emulator. Then find the location your app installed to and run “gdbserver --version" from the app path and let me know what it says? This will validate if the correct version of gdbserver is on the device."
So we are trying to solve this problem but I'm also asking here just in case.
Is there anyone who has magical solution for this problem?
I'll put a comment on this if I figure out how to solve this.
Thanks in advance.
** Following answer is from the manager of Visual Studio 2015:
You are only the second person who has run into this issue, and the first person that ran into it provided their everything works correctly when we run their .vhd on our machines so it appears to be some strange problem where gdbserver (which comes from the Android NDK provided by Google) crashes only when running on certain machines. Unfortunately the .vhd you provided does not appear to be the correct one it won’t boot for me. You can see the .vhd file being used by the emulator if you look under the settings of the emulator in your Hyper-V manager. .However given we got the other person’s .vhd you can hold off providing any additional information at this point. I’m waiting to hear back from the emulator team on if they have any ideas since this appears to be an issue only on specific machines since.
If you don’t mind my asking, if you don’t have a background in computers what inspired you to try C++ on Android? That scenario will be significantly more complicated than doing Java on Android.
It's been almost two months since I got this answer but I haven't got any additional response from them yet. So, I ended up quitting developing an application by using VS2015.
If you run into this problem, there are only two ways to go. Change your computer or stop developing application via VS2015.
If the project name contains spaces, the whole remote debugging fails. Visual Studio also creates weird paths. When checking out the "Blink1 for Raspberry Pi" template, I named the Project "Blink1 for Pi", which resulted in a path like this:
~/projects/Blink1?/for/pi/PI/for/pi....
And all the debugging failed. When I recreated this keeping the project name "Blink1", everything worked fine. It's a pity, that spaces aren't handled here...

I have Windows 10, fully updated.
I downloaded and installed Visual Studio Community 2015 last week for the first time, (previously programmed in Code:blocks, still installed) and selected custom install to allow for C++ and Python programming.
Installation ran smoothly, but VS always fails on launch.
On first launch ever, it said it was setting things up for first startup; asked me for sign-in which I did, at which point it briefly showed something about my profile before saying 'An error occurred while starting for the first time. Please restart Microsoft Visual Studio'. Imgur images of all dialog boxes here, including parts of a processmonitor log I estimated to be around the general time of the error.
Closing and restarting several times didn't help.
Uninstalling and re-installing didn't help.
Rebooting didn't help.
And uninstalling, running Ccleaner's Cleaner and Registry Cleaner, rebooting computer and re-installing VS didn't help either.
Repairing the install from Programs also didn't help.
I managed to find the exact same error on Google Search for VS 2013 but the only solution was where one person got a completely new OS and re-installed VS on that.
I tried the other suggestions they had including running:
devenv.exe /safemode
devenv.exe /resetskippkgs
devenv.exe /resetuserdata
devenv.exe /installvstemplates
devenv.exe /resetsettings
the first 3 took me to the same sign-in screen. Regardless of signing-in or not, or running VS from the Administrator Profile or not, these option always give the same failed on first startup error.
Installvstemplates gives an error saying the operation could not be completed, but /resetsettings finally got me into VS.
That's about all it does though, I can go to the home page and access options/menu buttons, but signing-in makes it crash and reload again (but it does sign me in and take me to the home screen)
Signed-in/not and Administrator or not, VS crashes on opening a new .cpp file.
When I click Start a New Project I get "Error loading type library/DLL.(Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY)). Closing VS and trying to open it normally from start menu still always throws the original error, despite working if I open it via /resetsettings.
I've also checked [HKEY_CLASSES_ROOT\CLSID{73B7DC00-F498-4ABD-AB79-D07AFD52F395}\InProcServer32] in Regedit and found it is apparently correct.
I also used devenv /log to generate an xml file of the process when I open it.
Just to mention I have .NET Framework 4.5-4.6 installed with VS as well.
Looking forward to any advice.
So, for anyone else getting the same problem, I haven't gotten any other advice, since this post.
If you're still having probs # this point the only real solution seems to be a clean install of your OS .
I can confirm it solved all my issues, with VS + some OS problems I wasn't aware of . I can only assume they might've been related, good luck.
Trying to launch the editor from Visual Studio 2013 Ultimate I get the following error in the title. VS says it's because it can't reach MSVSMON.EXE on a "remote computer", the weird thing is that I'm not trying to debug on a remote computer, but rather, on my own. My firewall is ZoneAlarm if that makes any difference.
Any help?
Edit: I've set all in and outbound communication to and from both unreal and visual studio in my firewall to "allowed", yet for some reason it still won't let me debug...
Edit 2: Disabling the firewall entirely does nothing at all.. The error persists
Edit 3: Uninstalling ZA altogether seems to fix the issue
Just a note, so far you've been chasing the wrong problem and have not yet gathered enough relevant facts. The dialog is very unhelpful, this does not have anything to do with a "remote computer".
Msvsmon.exe is used in this scenario because UE4Editor.exe is a 64-bit process. Visual Studio cannot use its built-in debugger, it is a 32-bit process. Debugging a 64-bit process with a 32-bit debugger is not possible. So it has a workaround, it uses the 64-bit remote debugger, C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\Remote Debugger\x64\msvsmon.exe. Basically works the same has remote debugging on another machine, except it doesn't use the network to connect to the debugger.
So your firewall settings and the considerable amount of trouble-shooting info about remote debugging you can find on the web or MSDN just does not apply in your case at all. You've been chasing the wrong problem.
Having an issue with msvsmon.exe when debugging 64-bit code is quite unusual, never heard of anybody having trouble with it before. You want to do a basic smoke test to check if it is really a problem with msvsmon.exe or it is actually UE4Editor.exe that puts up a fight.
Create a little do-nothing C# console mode app, just Console.ReadLine() in the Main() method. Project + Properties, Build tab, untick the "Prefer 32-bit" option. This ensures it runs as a 64-bit process. Press F5. If all is well then it starts running and you'll see msvsmon.exe in the Task Manager, Processes tab.
If that does not work either then something is interfering with the process interop between Visual Studio and msvsmon.exe. Usually anti-malware related, disable that first. Next thing to try is to start killing processes one-by-one with Task Manager to find the evil-doer. If debugging the C# app works okay then you have a good reason to visit the UE4 forum to find help.
Update your question with what you've learned.
Uninstall Zone Alarm and everything will be OK.
I have recently encountered a problem on my Windows 7 machine where I can't run an application with a specific name. Let's call it a.exe.
It is a C++ Qt based app and has been working OK for months but when I tried to run it today I got "The application was unable to start correctly (0x80000003). Click OK to close the application.". This happens for both 32-bit and 64-bit builds for Debug or Release.
I spent hours going round in circles checking dependencies and rolling back to previous versions without getting anywhere. I tried the software on a different machine and it worked, so it must be something on my machine...
I finally discovered that if I rename it to something else (e.g. a1.exe) then it will work :-S
I've checked the VirtualStore folder but couldn't see anything. Any other ideas?
Maybe your "known file extensions" are hided, and you are trying to access a.exe when actually the file name is a.exe.exe?
I have a cross platform desktop C++ app for Mac OSX and Windows, for which I'd like to collect debug info when a crash happens on a user's computer, so I can find out what the problem is and fix my code. On Windows I'm using visual studio express 2010 and on Mac I'm using Xcode 3 as IDE. I remember an online service where you could sign up and link your code with a library, so the app would upload crash info to the service, which you could then use to fix the app, but I can't find it anymore after googling for 10 minutes. Can anyone help?
Thanks!

Please see here for the google-breakpad project. I think this is what you need. I was going to use it for a project so I researched about it but then the project ended so I didn't have a chance to. You link your program with it and when the program crashes, it generates a crash dump that is not compatible with any of the platform-specific crash dump formats but has its own one. You can then analyse them with a program that is part of the breakpad project. As far as I remember, there is also a service that you can install, where the crash dumps can be uploaded. The service then can analyse and group them by reason etc.
Hope that helps.
I have searched and found no answer to this
I have a weird problem when running executables through developer studio (2008): a basic 'hello world' exe works OK when created through the usual dev studio project creation mechanism, but when trying to run a library based program the software crashes with STATUS_BAD_NETWORK_PATH. The program uses Qt and zlib behind the scenes and is written in C++, but (as far as I'm aware) is not dependent on any particular network locations on initialisation; we do have Sophos installed on the PC too.
The weird thing is that one cant even step into the main: the program fails well before this with the error. If we plug the network in, it starts up just fine ... The odd thing is this only occurs on a specific 64 bit Windows 7 machine.
Does anyone have any tips as to how to trace where the issue is? We've tried tracking using procmon but it is not very revealing; no obvious failures up to the point where the program crashes.
We have now figured out the answer. It transpired that there were 2 issues:
Firstly a wrapper .bat script that was launching developer studio was setting the PATH environment variable: a location in this path was being specified using a UNX style path (e.g. \\a\location\somewhere) rather than a mapped drive. The executables were not actually using this location but when the network was unplugged this it seems that this was disrupting things from dev studio
This, in tandem with a network configuration error on the PC, meant that deep down in the runes, something was failing.
So - advice if you see such an error
Check your PATH and make sure it is sensible
Look in your PC's configuration logs, and see if you can see any networking issues
