If you are using Windows, you should find either Notepad or Wordpad programs under Accessories.  Open either program, you will get a new blank page.  Go to File on the taskbar and click save.  Navigate to the desktop and type Poser in the name field.  Hit save.  Close the program.  Select the program you just save on your desktop, right click on the mouse to open the menu and highlight rename.  Select only the extension and change it from txt or doc to exe.  You will get a warning about renaming the file but just click ok and proceed.  The file will change into a Poser icon as if it is an actual execution program.
