VCS Simulator 5.1

all,

I worked with the similator without problem.

And yet I want to use it to do some screenshot and eduction and when I use the gui to start my cluster (config ok) nothing appears.
When i use CLI, i have an error :

C:\>hasim -start HERM1 -clus hermprod
VCS ERROR V-16-1-10590 Cannot start C:\Program Files\VERITAS\VCS Simulator\bin\hadsim.exe -sim HERM1 193
VCS ERROR V-16-1-10015 Cannot start C:\Program Files\VERITAS\VCS Simulator\bin\hadsim.exe please check file

any ideas ?

Regards,
Hervé
