unable to install or run C# application on client PC

I have developed a desktop application in c# & SQL server 2012 using Visual Studio 2013. I have included the reference for Microsoft.VisualStudio.DebuggerVisualizers and set copy local : true.
The application runs perfectly on client systems with windows 8, 10.
But its showing this error while installing on a windows 7 system.
- OS Windows 7 Ultimate
- already installed .NET Framework 4.5
- installed Report Viewer.exe 2012
- installed report viewer.msi 2010
- installed sqlclr types
- the system doesnt have any microsoft c++ redistributable , i am not sure whether it has any impact.
I checked in the assembly folder, but couldnt find the Microsoft.VisualStudio.DebuggerVisualizers.dll
Am I missing any prerequisites here? How to solve this issue so that i can install the application
Error Message

It needs the Microsoft.VisualStudio.DebuggerVisualizers.dll in the global assembly cache. The GAC is the area where libs are placed which can be accessed from all of the system.
It's kinda a ugly fix but you could place this lib in the same or subdirectory of the same directory where the application is.
Is it possibly that you haven't installed VS on that Win7 machine but on the others?

Unintentionally the Microsoft.VisualStudio.DebuggerVisualizers.dll had been included in the project reference. And in the client system the specified dll could not be found even after trying to install it. Hence I removed it from reference and then it worked perfectly fine without any issues. I guess instead of report visualizer i have included debuggervisualizer. It was a manual error.
Thank you for your support

WPF application doesn't run on another computer

I created a new WPF project. I copied the built .exe file onto another computer and tried to run the application. But nothing happened. It was just loading. Nothing more.
All my WPF projects do this thing.
What am I doing wrong? Has anyone any idea?
Edit: For somebody in the future: the question might not be clear. What I meant was that I created a simple WPF application with nothing in it and tried to run the application on another computer. I wasn't able to make it run. Just nothing appeared. I figured out that the Avast Free Antivirus was causing this problem. When the antivirus is turned off, it runs as expected. Even though it is no solution, at least we know, what was causing the problem.

You are probably missing the dot net libraries on the target machine.
For quick fix, download the dot net framework distributable for the .net version you compiled against and install it on the target machine. Here is 4.5.1 for example.
For actual distribution, look at creating an installer that will ensure all dependencies are installed with the application. InstallShield has a limited edition which may be included with your edition of visual studio

Try publishing your application using click once. You can do this by right clicking on your project > Publish > Specify the location to publish your application > Finish. Copy the files inside the Published folder to another computer and try installing by click the setup.
Note: The instructions I said above only works if you only have basic functions on your app. If your application uses SQL Server, you need to install it first on the computer that you will be installing your application in.

How do I publish my Monogame game?

Back then when I had Visual Studio 2011 installed, there was a "ClickOnce deployment" option in the project properties window that created self-extracting installation packages that also verified application dependencies (DirectX, ...). I have updated to VS2012 and switched to Monogame due to Microsoft cancelling any further XNA development. That also caused the "ClickOnce" deployment tab to be gone. Nobody I send the Release directory to (it includes some but apparently not all required libraries) can't get the game started - it always crashes, usually due to lack of some OpenAL DLL. Could you provide me with links and/or instructions on Monogame apps deployment/publishing? I've already tried Google but maybe I've overseen something.
I'm targetting Windows.

I found this article while googling for "Monogame Required Dlls":

Basically, besides the assemblies in your Release folder the user would need to have OpenGL drivers installed.

Run XNA 4.0 game on other machines

I checked here: How do I get an XNA 4.0 game to run on other machines?, but there's no real solution in it.
I created a completely empty XNA4.0 project, selected Release and compiled it, rar'd up the Release folder and sent it to a non-development PC. Got an Appcrash generic error.
Its probably something standard I'm doing wrong, but no idea what..
Can confirm that both .NET4.0, XNA Redist 4.0 and DirectX are installed on the other machine.
UPDATE: The empty 'new game' loads now, but I have made a program or six over the last years, each of which doesn't run on the other machine. Could someone perhaps link me to 'proper' referencing, assemblies, and such? Google dropped those words more than once in combination with my problem.
UPDATE: I asked a friend to test on his PC, at first, same error, but he forgot to install the XNA 4.0 redist. After that, my files were running fine on his pc. Still, they're not working on my own non-development machine, for some reason. Anyway, thanks for the suggestions, now that I know its local I can probably fix it myself. Suggestions are still welcome.

The end-user needs to have .NET 4.0, the XNA 4.0 Redistributable (not the full game studio), and DirectX installed.

Is there the Dot-Net 4.0 and XNA 4.0 framework installed?

Choose to publish the project and you will get an installer that check and install required libraries for you...

C# application crashes before start

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.
