Your question is unclear, maybe you should post code that will show example of where you are having problems.

Also post the error messages if you get any.

Do you really think that "is doing a problem" gives us any idea what your program is doing?

We cant tell why your cod isnt working if you dont show us the code that you are using.

Here are some people hat have encountered the problem before:

You should be able to resolv your issue. Just build two versions of your softeware, one for 32 bit and one for 64 bit (this is common in many programs) and you would be home free. There are other things you could try first though, please see the links.

My two cents:

1. Never go with Office Interop assemblies as it creates huge dependancy on MS Office Installation, without the office installed Interop doesn't work.
2.There are issues on 64 bit platform.

This would help you, a beautiful library I have seen so far.

The above library has zero dependancy on Microsoft Excel, you can deploy your app freely without the huge dependancy on Excel installation.

Again set your app to x86 specific and then deploy it on 64 bit machines.

Thanks,
