Short clarification and practical options that build on what , and already noted.

C# applications compiled for the .NET platform run on the Common Language Runtime (CLR); the compiled output is intermediate code that needs a matching runtime on the host machine. Given that constraint, common ways to deliver working apps are listed below.

Typical approaches:

  • Re-target the project to the lowest reasonable framework that still supports needed APIs (reduces how many target machines lack the runtime).
  • Produce an installer that checks for the required framework and installs it if missing. Visual Studio setup projects and ClickOnce both provide “prerequisite” mechanisms; third‑party installers (Inno Setup, NSIS, commercial setups) can detect the framework and run the redistributable silently. This keeps the user experience simple and avoids a separate manual download step. (This is the practical expansion of ’s suggestion.)
  • For environments where no install is possible, consider alternatives: run the app under an alternative runtime such as Mono (compatibility varies and testing is required), produce a native rebuild, or use application‑virtualization/packaging products that bundle runtimes with the app.

Quick troubleshooting notes:

  • An error naming a specific version (for example “v2.0”) means the app was built against that framework; either install that runtime on the machine or rebuild the app to target an available version.
  • Always verify installation behavior on a clean system (virtual machine) that mirrors target user systems so missing prerequisites are caught before distribution.

Credit: gave the core explanation about IL/CLR; was correct that a redistributable is what gets shipped with installers.

You have to have the .net framework installed. You can include that as part of your install progam.

Because the programs written in C# require components of the .NET framework, it is impossible to run a C#.NET program without it. The source code you write doesn't get compiled directly into any kind of low-level language, but into an intermediate language that must talk to the .NET framework.
As it's been said, you can always include the framework as part of your program's distribution. Otherwise, anyone can download it FREE from Microsoft.

Oh, and for you programmers out there, there's a very cool IDE called Omnis Studio, with a pretty powerful scripting language, that is very nice. It too requires a runtime (similar to the framework). Problem is, every computer that runs your program must have a runtime license from the publisher...at about $250 a pop!

Tell them to update their xp to sp2 (if they run xp of course), its bundled with it!
Any other OS shouldn't be used anyway :P

hi to run a .NET application in other computers you need atleast the .net framework redistributable pakage which is about 20MB in size.
