Hello all,

I am unable to start a simulation on PRIMO v0.1 on my lab computer: i7 14700k,  32GB RAM and windows 11,

however it works perfectly on my Dell studio with a core2 duo E6500 and windows 10,

I do not want to use the Dell studio as it is a  bit slower than the i7, but the i7 PC simply does not work! ( I have all permissions enabled and running admin)

here is the log file : -------------------------------------------------------------
