大侠救命安装DriverStudio2.6

以前装过2.6，后来卸载了，现在又想装，怎么也装不上，
最后出现一个对话框提示：
InstallShield Wizard Completed
The wizard was interrupted before NuMega DriverStudio 2.6 could be completely installed.

Your system has not been modified. To complete installation at another time, please run setup again.

Click Finish to exit the wizard.
怎么办？
