I do use this sentence in the windows command console:
c:\FlexLM\lmutil lmstat -c c:\FlexLM\SELicense.dat -a
Of course you need lmutil.exe and SELicense.dat in the c:\FlexLM\ folder to work.
Thank you very much for your prompt feedback, I'll try as mentioned above in customer site.
I have downloaded the sources, we'll give you an update latter.
Thanks & Rgrds
