I need a wix xml-code for building MSI

I need a script for wix , that I will compile into MSI. What should the installer do? It should not contain any files within, but it must copy some files from the directory where .msi file is. And also copy some files from the subfolder. All these files should be copied to the Windows directory. Also, installer must create an auto-start entry for the application file in the Registry, under the "HKLM" Root. On installer update, it must re-write all existing files in the Windows directory (in fact, to do the same thing as on install). On uninstall, it must at first, remove all files which were copied to windows directory. And second - to remove the specific file from the COMMON_DOCUMENTS folder IF IT EXISTS there. Details: The MSI is located in the folder \\PCNAME\sharedfolder\source\[login to view URL] In the same folder there is a file install.exe. There is subfolder: \\PCNAME\sharedfolder\source\data And there are the files there: \\PCNAME\sharedfolder\source\data\[login to view URL] \\PCNAME\sharedfolder\source\data\[login to view URL] \\PCNAME\sharedfolder\source\data\[login to view URL] INSTALLATION: 1) Copy file [login to view URL] from relative path to Windows directory as file [login to view URL] 2) Copy file [login to view URL] from data folder (relative path) to Windows directory 3) Copy file [login to view URL] from data folder (relative path) to Windows directory 4) Copy file [login to view URL] from data folder (relative path) to Windows directory 5) Write key to Registry (HKLM) to Run as string "[login to view URL] /autostart" - this will tell system to autostart application on Windows startup. UPDATE: To do the same things as on install (rewrite existing files). UNINSTALL: Remove all files which were copied to the Windows directory And ALSO - to remove the file [login to view URL] if it exists in the folder [COMMON_DOCUMENTS]\MYAPPLICATION\file4.dat. The installer should NOT create any shortcuts in the start menu, and in the Uninstall Programs list. Also, it should not have user interface. If for some case it is not possible in MSI to not include any application inside, you can use [login to view URL] as main installation application. But the rest files cannot be included into the msi, because they have no fixed content, so you must copy them. This installer will be used for quite installation of the software in local network using Active Directory. As a result of your work I need a wxs file from you. But for testing, you can send me an msi file.
