Zenon Editor v7.11 SP0 Build10238 can't be started!

Hi, :)
Zenon Editor can't start, however Runtime has no issue to run.
Editor is running well previously, however it can't be started now, no error message, no response, even re-installation can't solve the problem.
ZenSysSrv.exe, ZenDBSrv.exe, and ZenDBAdmin.exe are running.
Anyone can enlighten me?
Thanks
