Hi Amirreza,
maybo you have solved your problem with type 3157 already. Also I am not familiar with this type. However, one idea occured to me: Is it possible that your TRNSYS installation and your installed versions of type 3157 are in different formats, regarding 32 bit and 64 bit. The DLL files must be in the same format as the TRNSYS installation.
KInd regard
Doris
