Looks like you do not place file/folders to the correct positions.
The program should be installed in the program files folder (or its x86 version, if applicable). When the program is executed, it should not write files into that directory, but to %temp% or a specific folder in %applicationdata% etc. (you can use Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) etc.)
The next issue is 32bit/64bit. If your program does not rely on third party components, you need not care for that. If those third party components are also available in 64bit versions, you also need not care. But when a third party componentis available only in 32bit version, you must set the target platform to x86 (i.e. 32bit).
