I need to put my C# application onto a usb drive. It needs to be executable from there.
The problem is that it requires .net framework 4.0 to run (or possibly 3.5 - it uses OpenXML to open, modify and save .docx word documents, I'm not sure if its compatible with 3.5).
Having the program on the USB drive means there won't be an installer, which in turn means that I can't build in the prerequisites check that normally says "You need .net framework 4.0... install now?".
Is there any way I can build a check in to the application prior to the default error message from Microsoft and install .Net framework 4.0 from an installer on the USB drive (see: Where I can download the REAL Full .Net Framework 4 Standalone Installer? for links to .net frameworks installers).
I realise this question is a duplicate of Installing .NET framework from USB drive when necessary however, I don't really understand the question and on looking up ClickOnce Deployment I'm not sure how that can help me at all.
Thank you.
You can have a script in autorun that will check if there is a valid .NET and install it and then it'll run the app
vbscript to check if .net 2.0 is installed

I've developed an application in .NET 5.0, also, I've a Setup Project to install this application in my clients.
My steps are:
1.- Publish the .NET 5.0 Application.
2.- Compile the Setup project.
3.- Install the setup.exe generated in "2" in the client.
But when I try to install the program in my client, windows says "This installation requires the 5.0.0(x64) version of .NET Desktop Runtime... So I've to download and install the SDK in every client.
My question is: There is some way to avoid this SDK installation? Can I embeed the .NET Desktop Runtime in the .NET 5.0 App or in the Setup Project?
Thanks in advance.
See .NET application publishing overview, specifically publishing a self-contained application. That way all necessary framework files will be included in your application, and you will not the framework to be installed. This will increase the disk requirement a bit if .Net 5 is already installed, since some files will be duplicated.
The alternative is to bundle the the .Net framework installer in your installation script. This will cause the setup-file to be quite a bit larger, unless the script downloads the framework on demand. But it may save some disk space in case there are multiple applications that use .Net 5.

I have created Sales Management System using C# and MS SQL Server 2012. This is working fine. All I want to know in how can I create an exe so that this can be installed in another machine without any .NET Framework.
e.g. it should say like SalesManagementSystem.exe, and I should be able to install it in any machine.
Just download the Setup project templates and create an installer:

See my extensive guide here on how to make an Installer (one that upgrades itself as well):
Install to same path when upgrading application
A .Net application will never run without the corresponding framework installed. But depending on the target OS the framework is already installed. Please check the release history at wikipeda. There you can see which .Net version is already installed in which windows version.
If you want to deploy a single executable you have to embed all your depending assemblies into your executable as a resource (plenty of questions and answers are already at SO) and load them by overwriting the AssemblyResolve event.
If you want to create a windows installer take a look at WiX.
You cannot just skip the .NET Framework on the target machine - it is needed to run your program. The exe file, produced by the C# compiler contains MSIL, which is understood by .NET Framework, as opposed by the destination OS - be it Windows or any other.
Having that said, your best bet is to write an installer for your app and
distribute the .NET Framework distribute the .NET Framework along with it. When launched, the installer might check what is the installed version of the .NET framework on the target machine (if any) and respond appropriately by installing whatever it is needed for your application.
You can use WiX to author an installers.
I use VS 2010 C# Express
The file is digitally signed (signed/verified with signtool)
Target framework: .NET Framework 4 Client Profile
.NET Framework 4 Client Profile is installed
I'm uploading the exe to a simple static html page
If I (or anyone) click on the download link get the message above
Right-click -> Save Target As... works OK
I can run the file without issues after downloading
May I ask why you are targeting .NET 4.0 Client Platform specifically? Why not go ahead and target to one of the 4.5 versions? Is there a requirement to target a discontinued release of .NET?
Within that link and this one under the 'Additional Information' section, there are statements that indicate an 'in place update' to .NET 4.0 is made to migrate an already installed .NET 4.0 Client Platform to the .NET 4.0 Full Install -- there doesn't appear to be anything written to indicate that 4.0 gets installed by the 4.5 installer, if it's not already installed on the system.
Therefore, all machines with .NET 4.5 installed would have replaced the mentioned 'target framework' of .NET that you're building with something that no longer exists on those machines ... which I believe might account for the popup error received. Can you, at least, try to target one of the 4.5 versions of .NET and update the executable to download on your server? Try again and see if the error goes away? If it does, then the problem that you are facing pertains to .NET Client Platform not (or longer due to 4.5 update) being installed on the client machines.
If that's the case and .NET 4.0 needs to be targeted, then you might need to target the Full 4.0 version instead of the Client Profile version. Or just move to one of the 4.5 versions.
I'd venture to guess that the problem is not within the executable itself but somewhere in the delivery of it into the web page or in the delivery of it back down to the end user; especially considering the program will run without issue once it's downloaded.
Have you completely vetted that process? You mention 'simple static html page' - elaborate on that a bit and you might get more suggestions that will lead you toward a proper solution. Web server used? Technology involved? Personal machine running apache or the like? or some website generator? or something like Wordpress? or some other web hosting company and their products? If the problem lies therein, then further details would be nice to have to help you deduce what is causing issue.
As I'm sure you're aware, that particular error message appears to be presented mostly to products that utilize products created with or included libraries requiring .NET 2.0, 3.0, or 3.5 - since they are (by default) no longer pre-installed on newer systems released with Windows 8+ ... a simple test to rule out the possibility would be to simply install the .NET 3.5 installer and see if the problem magically goes away - if it does, then you may need to do a bit of further research on the 'delivery mechanism' - read, web server used - technology it requires - etc ...
If that's way off ... perhaps this is an x86 vs x64 problem? 32bit app running on 64bit OS? something along those lines? A simple test would be to create 2 executables: one that is configured to build all output as x86 and one to build all output as x64 - see if both behave the same or if there is a difference, and move forward from there.
I believe that in this situation, you will need to play around and run a few tests before getting to the bottom of it. Good luck to you.
My programming language is C# .Net 3.5 and I may have to install my applications in very old client systems (windows XP-SP1 and above) and may be that those systems do not contain any version of .Net (or even Windows-Installer-3.1) in them.
I have worked on VS-2008 deployment projects on and off since some time and I have some working knowledge of it.
I want to write a deployment project in VS-2008 but I have 2 questions :
Can a VS-2008 deployment project containing pre-requisites run on a system without any version of .Net (or even Windows-Installer-3.1) pre-installed in the system ?
How to create a boot-strapper installer to run in systems without .net pre-installed in them (boot strapper will install all pre-requisites including .net and other 3rd party run times) ?

Yes, the EXE bootstrapper which handles prerequisites doesn't have any dependencies. So you can safely add Windows Installer and .NET Framework as prerequisites in your setup project.

Here is an article which may help: http://setupanddeployment.com/uncategorized/custom-prerequisite-visual-studio-setup-file/
You can use Salamander .net linker. I don't exactly understand what it does but what I know is that I was able to pack the necessary reference and the program into 1 folder. When I move the folder to a computer without .net framework installed, it was able to run.
The demo version of the program will give u nag screens every time u run the packed program.
The side effect of doing it this way is my program file size increased from few KB to 40MB.

You need to have .Net version installed on the client system.
Else it wont works.
Because even to start your application your application will search for CLR 2008 version.
You can do one thing. If you dont want to install .Net Framework, please develop your application in lower version of .Net framework.(May be .Net 2.0 will work without any requirement since it is XP SP1)
No, because there are not just DLLs, there is common language runtime needed to execute your program. Read the great book by Richter to better understand what happens when you create a program using .net libraries and its lifecycle.
By the way, i'm not quite sure, there must be some older version of .net installed with SP1. So may be you consider changing your application to use .NET 2?
UPDATE
May be you want to add .NET to your setup as prerequisite? You can add them without creating bootstrapper packages. See the article: http://www.codeproject.com/Articles/35976/Add-Prerequisites-of-NET-Framework-in-Visual-Studi
Is there any way to make a WPF Browser Application prompt to install .NET Framework with ClickOnce like a regular installable WPF Application?.
Those publishing options are locked when the HostInBrowser property in the project file is set to True, which is necessary for the application i'm developing, however i need to make the installation of dependencies user friendly, and possibly from the .net framework installer already hosted in my server, as it would cut down greatly the use of bandwidth.
The program is intended to be used in intranet, as a "web page", by placing shortcuts on the desktop of each computer (which is done at the first run of the app), but most of the users don't have .NET Framework 4 installed.
is there any way to accomplish this without converting it to an installable wpf application?
Thanks in advance, Jesús.
No ClickOnce requires the .Net framework, because it's a component of it.
All ClickOnce applications require that the correct version of the .NET
Framework is installed on a computer before they can be run
You can however set a prerequisite which is a higher version of the framework, provided they have at least version 2.0 to begin with.
Commonly a bootstrapper written in managed code is used to overcome this limitation. You could use MSBuild for this, dotNetInstaller, or other third party tools. I've used dotNetInstaller a few times a recommend it, it's very flexible.
