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

[Brandon Hathaway]

Thanks David,

It looks like the TESS DLLs do have _64 appended to all (except for
"TESSArchiveDLL_v17.2.01_Release.dll"). TRNOPT is indeed TRNOPT17.exe
though, so perhaps that was just a mistake for that one library when
putting together the packages for the libraries we had selected.
