Thing with "%USERPROFILE%"

Hello, i currently trying to make an installer and i wanna use the "%USERPROFILE%" property that Microsoft uses, but is not determinated at Autoplay Media Studio, so i wanna use it because if i only set "C:\\Users\\Administrator" as a Path, it will don't work at other Microsoft Profiles that has Admin rights but with custom names, and then i wanna fix it. So my question is... ¿Is there any code or form to introduce that profiles to make it install the responsible files of my project on it? Thanks for reading and i hope you all answer my question. Regards. ​
