thank you françois
with your help i succeded:
- i had to uninstall, delete all file an then reinstall matlab (i had different versions of matlab and different file of brain storm)
and brain storm in a different file - i had to put brain storm file outside of program file
- run matlab as an adminstrator (right click move)
an no i passed many problems, cat12 is running
but it is openMEEG that has a problem
