Yes sir. I have completely uninstalled and reinstalled the package. Still having the same issue. 

Last week i faced an issue like the "ANSYS WORKBENCH" was launching but when i tried to maximize from the taskbar, I was unable to see the window. 

On seeing some online solutions, i used sfc /scannow in command prompt to resolve it. After that workbench started working well.

Would that have caused a trouble to spaceclaim.exe
