Depending on the .NET Framework you designed your application with, if it is designed in vb.net, then as deepdotnet mentioned, you will need the .NET Framework installed on the foreign computer.
View the following links for the 2.0 and 1.1 .NET Frameworks.
Microsoft .NET Framework Version 2.0 Redistributable Package (x86)
Microsoft .NET Framework Version 1.1 Redistributable Package
I have not had any use to install a .NET Framework on any foreign computers for running my applications, so I do not know for certain that the above links will fix the problem.
The best suggestion I can offer is that you should always have the .NET Framework along with your software, possibly on a CD.
sumit.khera's reply of "give me the path by which i can download the vb.net software", if understood correctly, you can download Visual Basic.Net from the following link.
http://www.microsoft.com/express/Downloads/
Otherwise, if the reply was towards locating the .NET Frameworks, i hope my previously posted links are of use.
