This is incredibly strange to me. Neo4j won't start a second time unless I restart Windows.
I installed neo4j Community Edition 3.0.3 on 64-bit Windows 7 and followed this youtube tutorial https://www.youtube.com/watch?v=Foj2tzq84DY. The tutorial was embedded in neo4j's site https://neo4j.com/download-thanks/?edition=community&flavour=winstall64&release=3.0.3&_ga=1.203356307.385208157.1468345542. Even thought the video lists 2.3 it's linked by Neo4j 3.0.3 download and worked fine for 3.0.3.
Everything worked like a charm. I played around with it for a while and things worked fine. I then shut it down, by clicking on stop in the little gui launcher. When I tried to start it up again, through the start menu, nothing seems to happen at all. I went into the Neo4j CE 3.0.3\bin directory and tried running from there, but I see no error messages, no log directory, no error dialog. I just seems to do nothing. I've also tried "neo4j-ce.exe start" and "neo4j-ce.exe restart". Nothing seems to work.
I checked windows services and didn't see any services starting with neo4j. Don't know if default setup runs it as a service, but if so, maybe it's under something else?
I have been able to get things to start up if I restart Windows, but that's a royal pain and cannot imagine that's intentional.
I do see that there's a jar in the bin directory, so I imagine I could start it with a java command, but I don't know the specifics. However, it's most disconcerting that there is no error message at all. I imagine that something didn't shut down properly, but at this point I have no idea what might be going wrong.
Any help is greatly appreciated.
I don't know if this is a bug with the launcher for the community edition of neo4j on windows 7 or not, but what I've found is that when you close the launcher dialog, it does not kill the neo4j-ce process. Thus, since the process is already running, albeit in a stopped state, it won't start again. The challenge there is, of course, that the dialog is gone and you can't click the start button to essentially connect to a database.
The solution is to go into Task Manager and end the "neo4j-ce.exe" process.
Once that is done you can start Neo4j normally.

My SqlDeveloper app has been working normally since installation. Now, when I open it, everything seems normal ... until it quits itself. I have enough time to see what's happening, then the window just closes itself.
Here's what I've tried:
-deleting the two folders in AppData\Roaming like other posts say to do
-uninstall + fresh reinstall
Neither worked. I was shocked when the reinstalled version exhibited the exact same behavior. If it's not obvious, such an insidious problem is happening on a Win10 machine.
UPDATE - thanks jeff - here's my CL output
I also have a log file, but it exceeds the SO limit
Mostly likely the windows video driver is crashing the java jvm.
Start SQL Developer from the /bin folder.
WHen it 'crashes', inspect the CMD window for any error messages or the java stack dump.
This is discussed on our product forums here.
I have a Clickonce app from Visual Studio 2015 SP3 that is published to the network server and used in-house only. The program works just fine when launched from Visual Studio. It runs just fine on a Windows machine that does not have the 1803 update. But once a machine updates to 1803, the application no longer starts. I get the "Checking for updates..." window then nothing. On a fresh install, I usually get the Smartscreen telling me the program may be dangerous. It doesn't get that far.
I've created the Clickonce from a computer with the 1803 update and the problem still exists.
I've disconnected the machine from the network. The application starts but then has no database access and it needs the database. It's also written to hide buttons that would use the database to prevent users from trying to do things that require it.
I found a workaround (third paragraph) at https://social.technet.microsoft.com/Forums/en-US/7cbd16f5-526e-4b0b-a186-3ebf41b7b349/smartscreen-prompt-does-not-show-for-clickonce-app-since-windows-10-update-1803?forum=win10itprogeneral. When I start the application from the directory mentioned, I get the Smartscreen and can tell it to run anyway. Every time I click the desktop icon, it works just fine.
If a new release is published, the new release is downloaded and the program updated, but the Smartscreen no longer appears and the application never starts.
So somewhere between installing the latest update and the Smartscreen, this is failing. Anyone else experiencing this and have an idea as to why?
Yes, frustratingly I also experienced this today. Presumably a security update that they'll release another patch for given this is quite a pain for developers and users of small business apps.
Rather than disable Defender or SmartScreen I chose to add my deployment website to the Trusted Sites in Internet Explorer and that then re-instated the warning dialog and my app updated and ran as before.
Really annoying given the nature of the issue and how long it took to figure out, but at the same time I had to use IE today, which is a rare event nowadays.
This works for me...Warn doesnt warn anymore...
After running in the same problem, I just found that my application was going to halt after a stupid uncaught exception.
Despite the fact that the image below is in Portuguese, Event Viewer shows the right error cause.
In my case, was a corrupted settings file!
It appears as though some subsequent Windows Updates have fixed the issue on several of our PC's that were previously experiencing the issue.
Check for the updates listed here.

Running winver.exe will show you which build you have.
I made a minor change to a legacy Visual C++ / MFC app built with VS 2008. I changed some UI resources in the .rc file and compiled without any problems, then deployed it on my client's system. However, the program which was previously doing fine now fails to run on exactly one of their servers. It works fine on my laptop and on their other servers, many of whom are basically identical to the one having the trouble.
The weird thing however is that there is absolutely no error message whatsoever. No message box, no errorlevel set (when run on command prompt), no Dr. Watson entry, no nothing.
It's an MFC app that does not really comprise anything very special. It does link in some external libraries – e.g., some old version of the Xerces C++ XML parser. But this is probably not too relevant, right?
The program has a class derived from CWinApp, and I tried to add some logging in its constructor. Based on this, it looks like not even this constructor is reached.
The server in question is running Windows Server 2003 Standard Edition Service Pack 2, and we are trying to run the program in a Remote Desktop session. (Because of the client's environment, I cannot easily test in a console session right now.)
I reverted my changes from version control, which did not help – but I do not know if I had built myself the previously installed version (which ran just fine even on this server) or if it had been built by someone else.
Have also tried to reinstall the Visual C++ runtime libraries and of course reboot Windows, but neither helped. Now I'm really running out of ideas... Any clues on what I could try or check?
Probably some error occurs but is surpressed e.g. empty catch() statement or similar.
You could try and install Debugging tools for Windows WinDbg to see if you could get more info when trying to run it. Since the download is rather small 25Mb maybe it is possible to install it on your client's PC.
But first check the eventview log for your app, maybe there is something in there that can shed some light.
I am writing an application using Delphi 2010. I would like to have my application start up when windows starts up. I need this to work in the latest versions of Windows XP, 7.0, and the latest servers.
Would storing it under the following key work, or do i need to do something else?
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
thanks for any help
That will only result in it starting when the user running the installation process connects. If you want it to start when Windows starts then try under HKLM.
Be aware that these Run key entries execute when a user logs on. To launch a task on startup, it's better to write windows services, which is quite easy to do in Delphi.

I'm trying to get Redmine working on Windows/IIS 7. I've found several walkthroughs online, but none of them work on my Windows Server 2008 R2 box. I got a simple app (create app, no customization) to get as far as RoR error, but Redmine itself shows a 500 error (ruby.exe exited unexpectedly). I installed sqlite since some guides mention that, though Redmine uses MySQL by default. I started with the Bitnami installer and tried to customize for IIS, RorIIS, FastCGI, lots of things that look like they should work, but this problem is killing me.
If I run ruby.exe from the command line, passing it the path to the dispath.fcgi file I get an error: "The procedure entry point SetMagickMemoryMethods could not be located in the dynamic link library CORE_RL_magick_.dll". I had to install the rmagick gem myself which seemed strange since everything worked perfectly under Apache. I really thought it would be a smooth cut-over since it's up and running already and just changing web server.
Any help is much appreciated.
I've tried a lot to install Redmine on Windows environment under IIS. There's very little (or none) documentation about it. Lost many days on this. In the end, I decided to stick to the Bitnami stack of Redmine. The only caveat is that we had to use another port (8080, in our case), that's it. I gave up the idea of integrating Redmine/RoR with IIS and never looked back. Everything is working great in production now and everyone is happy about it around here.
Sorry I can't give a better answer than that, I'm just sharing some recent experience. I was obsessed about integrating RoR/ISS until I realized it was not a real requirement, it was just something I stuck into my mind. Think about it.
