[TRNSYS-users] Using TRNOPT with 64-bit TRNSYS install

[David BRADLEY]

Brandon,

  The TESSLibs release that goes with Trnsys18 normally has a 
TrnOpt18.exe in it, which is set up to work with the 64-bit Trnsys18. It 
sounds as though you might be using an older TESSLibs release or one 
that is intended for the 32-bit version of Trnsys18. It might be worth 
checking in your .\Trnsys18\UserLib\ReleaseDLLs\ directory to make sure 
that all of the TESS Library dlls that are contained therein have "_64" 
in the file name. If they don't then please email me and I will get you 
access to the libs that are compatible with 64-bit v18.

kind regards,

  David
