请高手帮忙，环境变量设置问题！急！

mycourage2005

我运行一个可执行文件，出现了问题如下：
  [root@abc bin]# ./launcher100
./launcher100: line 73: /ansys_inc/v100/commonfiles/Tcl/bin/linem64t/wish: cannot execute binary file
The ANSYS Launcher could not be started.
The most likely reason is that your DISPLAY environment
variable is either not set (i.e. issue setenv DISPLAY
dev:0.0 where dev is your device name) or is set to a
device that is not accepting the connection.

应该怎么解决啊？请高手不吝赐教 ！我先谢谢了！
