I found this: http://www.minitab.com/support/answe...r.aspx?ID=1848 had solved my problem.
The point is there is something wrong with Microsoft Windows Script 5.6, whether it's corrupted or outdated. All you need to do is reinstalling it. Here are the links:
- Microsoft Windows Script for Windows 98 ME and NT (http://www.microsoft.com/downloads/d...displaylang=en)
- Microsoft Windows Script for Windows 2000 and XP (http://www.microsoft.com/downloads/d...DisplayLang=en)
