Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.

Any one give me ideas.

What I have tried:

The best idea is for you to debug your program to find out where the error occurred. No one here can guess what it is doing.

We can't tell you: a C# application compiled for 32 bit EXE will run fine on a 64 bit OS without changes, provided that all the required DLL assemblies are provided.
And debugging it will be difficult unless you install VS2010 on the target machine as you cannot run 64 bit apps on a 32 bit OS, and it's likely to be a missing DLL or a 64 bit DLL instead of a 32 bit.

So start by adding try...catch blocks to your application to report the problems with the exception detail and see if you can narrow down where the exception is happening, and what it is related to.

We can't do any of that for you: you are going to have to at least gather a significant amount of further information before anyone can!
