Hello,

I use Windows, and I'm trying to run openfast_x64.exe with a NREL-5MW.fst file. Attached NREL-5MW_fst.txt

It starts to run the simulation, but it fails looking for the libdiscon.so file. Since I'm running in Windows, shouldn't it be looking for libdiscon.dll file instead? Here's the full error

You can change the path to the library in the ServoDyn input file. In your case, it is NRELOffshrBsline5MW_Onshore_ServoDyn.dat alongside your main OpenFAST input (.fst).

Perfect, that worked. Thank you for the quick assist!
