I have a .NET 3.5 (C#) application, but interestingly it does not run on Windows XP. I have checked .NET Framework 2.0 SP2, 3.0 SP2, 3.5 SP1 are installed. When I run the application, no error message pops up. It just does not run. What could I try out?
this is may be because you have build this application on 64 bit machine please try to compile it over 32 bit machine and re run
You could install WinDbg (it has the advantage of being quite light, not too invasive, not like a full Visual Studio install), and run your .EXE from its console. WinDbg will break on the first exception. You will be then able to dig out further using something like SOS (WinDbg extension for managed .NET programs).
If your application requires the full ".Net Framework 3.5" make sure so it isn't the ".Net Framework 3.5 Client Profile" that is installed.
This have fooled me more than once...
Check if you have "appname.exe.config" file next to your app, or, in some cases, it have helped moving app in different drive/folder.
Folder path containing some language specific symbols might allso cause some compatability issues or runtime errors on some systems.
Have you copied all necessary DLL files with the EXE file? Except those already included in the .NET framework, of course.
If so, you should check the event log to see If you can find any hints. You can also use the PDB files in a test period bexcause this will provide more info to the exception and event log.

I have a C# project in VS12/WIN7 but when I try to run it under windows server 2003, it throws an error that it's not a valid WIN32 application. I have tried many configuration, also changed to Any Cpu from Configuration Manager, but it won't work.
This project has some socket and threading code...
How do I fix it ?
Judging by the comments to Ben's answer, you are targeting .net 4.5. This is your problem. The issue is that .net 4.5 is not supported on Windows Server 2003.
Since you need to target Server 2003, you need to target a .net version that supports that OS. The highest .net version to support Server 2003 is .net 4.
So you should change the project settings in Visual Studio to target .net 4. This MSDN article describes how to do that in Visual Studio. In summary you open the projet properties, navigate to the Application page, and set the target framework drop down.
If there is no bit-ness problem as mentioned in OP then you must check to which .NET version targeting your project and try to install appropriate version on Windows server 2003. Or target (if it is possible) to the version of .NET which is available on Windows server 2003 machine.
Try using editbin to change the minimum required OS version. That should fix the image-not-recognized issue; but you may run into other problems later.
For example:
EDITBIN myapp.exe /SUBSYSTEM:WINDOWS,5.01 /OSVERSION:5.1
Note: This doesn't address the root cause, so it shouldn't be treated as a final solution. It is, however, the best way to determine whether the failure is caused by the "minimum required OS" field in the executable header. Also, by continuing past that check to the actual startup code of the process, it may uncover the reason that the executable was marked to require a particular Windows version.
Really, it is a bad idea for any toolchain to use the "minimum required OS" field, because the defacto meaning of that field is "display a message about an invalid image". And the number of deployed copies of Windows versions up to and including XP effectively make it impossible to restore the intended meaning (it's not feasible to patch all of them with a better error message).
A version check and meaningful error message during application startup is far better.
I have an application written in C# and built using Visual Studio 2005 on winXP. It is working fine on winXP. If i try to run it on win7, I am getting an error called ".NET Framework Initialization Error." "Unable to find a version of the run time to run this application." Application target framework is .Net 2.0. How can i make it run on win7 ?
Try going to the files properties and go to compatibility then click on run in compatibility mode and then click on windows xp. this should fix the problem.
here's a screenshot to help. Ignore the fact that the options are blanked out they shouldn't be on yours.
try to Remove the .Net framework from your computer and then install .Net framework components through Windows Update .

I have a standalone tool developed in C# Visual Studio Express 2010.
My problem is that this tool will fail to start on machines having no .NET installed, and asking for .NET 4 on machines has .NET under 3.5 or lower.
What I basically want to do is to install .NET 4 from my application before the main script runs. I can write a program to download it from an official webpage, also to run the installer etc. But the main problem still exists, the app won't even reach the download part as it won't run on machines...
I've googled around and found that you can include dll-s etc., but I still doubt I can proceed without a proper .NET installation. So how can run dotnetfx.exe with my .NET dependent application?
Your attention and ideas are much appreciated.
Cs.
Use ClickOnce - it takes care of dependencies when configured correctly and comes integrated/free with VS.
EDIT: So vs express editions don't support setup projects. Plan B: wix.
simple. your installer must not be a .net application. just write your own c++ version or use some existing application. here is a link to show you how to do silent installs of .net 4. just include the setup application with your program. I would be very surprised if some of the msi installer tools out there do not have .net installation support.

I come to you because I'm desperate. I've developed a GTK# application in C# with the latest MonoDevelop. It's built for .NET framework 4.0 / x86, and the only external library it uses is the official Mysql .Net connector. It's meant to run under Windows XP.
It's the first application I make with this IDE. I was very happy with the results and the development time, but the deployment is a real headache.
It works perfectly on the development machine. The debug is clean. Everything's okay.
Then, as I couldn't find any information about the deployment, I installed a clean XP to try it and see what do I should install on the client's machine.
I've installed the SP3, .NET 4.0 and copied the release package with all the DLLs mentioned in the build log (that made it work outside the MonoDevelop in the development machine). But I'm getting a "the application has encountered a problem and needs to close" error, with no exception, in kernel32.dll, offset 0012aeb.
I've tried to install the .NET 3.5 before the 4.0, updated IE (just in case...), copied more GTK# and Monodevelop DLLs to the exe's folder, installed the Mysql .NET connector, installed Mono 2.8... But nothing. Still getting that unexplained error.
Google and StackOverflow searches didn't help me. I've researched and tried a lot of things in the last twelve hours or more without moving from this machine.
Do you have any advice? What can be causing it? Is there any way to debug the exe (without installing VS...)? Does anyone know what are all the dependencies of this kind of executable?
WinDbg can help you figuring some JIT trouble...
Even though it aint intuitive and require skills, Worth a try. might pop something up.
If it's meant to run under Windows, then you should probably compile it with the Visual C# compiler.
However, more related to your problem - get a debugger in your deployment machine and run the application on it. This is the best way to figure out the problem because we really can't guess it.
Mono Application Deployment Guidelines
There are several options to installing Visual Studio on your production machine, one of them is the Remote Debugging Monitor. It does not require a Visual Studio installation. You can copy the files from your development machine to your server. I've got them under C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Remote Debugger.
You can also use it for Remote Debugging of a Project Built Locally.
I'm working on a program in Visual C# 2010 for a friends company and it does not have any .NET installed. I know you can download .NET 3.5 or 4 from Microsofts site, but the accounts that the program will run on will not be able to install anything. Is there a DLL I can download and then place in the programs folder to make it work? Or any other alternative that does not include installing things or downloading things.
Edit: Disregard the 5mb limit: I had mean that if I have to download any program on the computer the program will be executed on, it should be below 5mb. The final application can be double or triple the original programs size.
Thanks,

Let me answer this directly so that you don't waste neither your time nor your friends: No there isn't other way other than properly installing .NET (or rewriting your application with unmanaged C++ code which is unlikely something you are willing to do). Not to mention that most Windows PC should already have at least .NET 3.5 installed through Windows Update.
The .NET 4.0 Client Profile is 41MB and that's the minimum you get away with.
While there are some options for running .NET applications without installing the framework properly (e.g. VMware ThinApp), I very much doubt that you'll find anything that fits in 5MB...
Heck, just mscorlib from .NET 4 is 5MB, then System.dll is nearly 3.5MB.
If your application can run on top of Mono, you can try using mkbundle, normally the resulting exe file is relatively compact.
Xenocode (now called Spoon Studio, I believe) allows you to deploy a single executable without previously installing the Framework.
It uses some kind of virtualization to achieve this. I don't believe it would fit in just 5 megs - but I might be wrong.
If the framework has not been installed, there will be no interpreter/jitter and .NET programs will not run.
You need to install the framework in order for .NET software to run.
