    <p>Marie-Hélène,</p>
    <p>  I do not think that the name of the DLL is the problem. 64-bit
      software (which Trnsys18 is and which Trnsys17 was not) is much
      less tolerant of floating point errors (divisions by zero). I
      suspect that there is a division by zero going on in your code
      that is causing the invalid floating point error. The division by
      zero was probably there before but the 32-bit version of the dll
      was better able to recover from it than the 64-bit version of the
      dll is.</p>
    <p>kind regards,</p>
    <p> David</p>
