Missing .dll extension files

Hello everyone,

I'm trying to run a numerical modeling software that requires openmpi extension files to run, but I'm getting this error:  “*/PADCIRC.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory”

I tried looking at the error through another road by running: “cygcheck */PADCIRC.exe", and I got these two messages:

“cygcheck: track_down: could not find cygopen-pal-13.dll

cygcheck: track_down: could not find cygopen-rte-12.dll”

I checked the cygwin website and the only .dll availables to install are cygopen-rte-40.dll and cygopen-rte-40.dll. Does someone know where can I find the remaining extension files?

Best
