Question

See more:

We have developed our project with the following technologies Visual
C#, Visual C++ and C Language. When we tried to execute our project in
client machine, It works only if the system has Visual C++ installed.
Otherwise it throws an Unhandled exception.The Visual C++ program
which we have developed is dependent on 4 native DLL such as
mscorlib.dll, microsoft visual c.dll, system.dll and data.dll. Visual
C++ project does not load the above mentioned assemblies during run
time.

So we kindly request you to provide some inputs on this to proceed further.

The visual C++ code of our application get data from C# and pass it to C program which is unmanaged. Mainly it converts managed and unmanaged data through dll export.

If you mean Visual C++ for native platform, the computer of your customer needs just two things: .NET Framework of required version and one more thing: Microsoft Visual C++ Redistributable Package of required version for the instruction-set architecture of the customer's computer. You can download appropriate version from MSDN.

For example:
http://www.microsoft.com/en-us/download/details.aspx?id=5555[^],
http://www.microsoft.com/en-us/download/details.aspx?id=14632[^].

Of course you don't need to install Visual Studio. Usually, you also are not licensed to do so.

[EDIT]

To find the ends, you can use the free Microsoft utility "Dependency Walker" ("Depends.exe"). Please see:
