Chun Kwong, As the error text printed in the *.log and *.lst files explains, you need to move all of your external DLLs from the ..\Trnsys16_1\UserLib directory to either ..\Trnsys16_1\UserLib\ReleaseDLLs or ..\Trnsys16_1\UserLib\DebugDLLs. If you are using the standard version of TRNSYS and have not recompiled the TRNDll, then move all files with the extension *.dll from ..\Trnsys16_1\UserLib to the \ReleaseDlls subdirectory and delete all DLLs that are at the root level of the ..\Trnsys16_1\UserLib directory.

I have gone through the .lst file, but could not find any explanation of this error. Can anyone advise how I can rectify it? Thank you!
