Not Able to Access the Properties of Workspace and Target

Hello

I have install PB 11.2 Build 9027 on my laptop ( Winows 7 (64 bit))). PowerBuilde is open and able to see the existing code.

But when I am trying to access the properties of Workspace or target for Source code control Setup, Properties will not come and nothing happen, I am not able to view the properties of Workspace and targets.

One more think I notice ,when I was trying to create new application (File > New > Target Tab > Application)  then window will not open.

Please provide me some suggestion on this issue.

Thanks
