System Requirements

RTW requires Microsoft® Windows XP or Windows 7, and Microsoft® Excel 2003 SP3, Microsoft Excel 2007 SP2, or Microsoft Excel 2010 SP1.

The installation requires approximately 25-60 MB of disk space as a single directory, depending on how many engines are installed. The installation of a single engine requires between 25-30 MB.

The RTW installation program places all product files in the install directory, makes some Registry entries, and places a few ActiveX controls in the system directory %SYSTEMROOT%\system32.

User settings such as personal favorites, history, and preferences are stored in files which are read by Microsoft® Excel at startup. In Windows 7, these files are saved in %USERPROFILE%\AppData\Roaming\Vistasource\RTW\ and can be read in any text editor, such as Notepad or Wordpad. In Windows XP, these files are saved in %USERPROFILE%\Application Data\Vistasource\RTW\. The files can be read in any text editor, such as Notepad or Wordpad.
