Xmanager Passive can't be runned [1]

hi , everbody, I got a error:"Failed to retrieve information required to run the program.Please try reinstalling Xmanager Enterprise" when i want to open the Xmanager Passive. I can use the Xmanger shell to connection my centos 5.5,
and I had set the DISPLAY=192.168.214.21 the 192.168.214.21 is my localhost's IP . sombody can tell me why?

Program Ver. : Xmanager 3.0
Connect Method : Other

You need to have admin right to run this program. Try running the application with Admin right. Right click and select "Run as Admin..".

Also, you shouldn't assign the DISPLAY variable. It is assigned automatically by Xmanager.
