Ros Installation Win10 | rosout.exe not in directory

edit

Hello Guys,

i installed ROS Melodic on Win10. Now when i run "roscore" the following error is displayed to me:

←[31mERROR: cannot launch node of type [rosout/rosout]: Cannot locate node of type [rosout] in package [rosout]. Make sure file exists in package path and permission is set to executable (chmod +x)←[0m←[31mRLException: failed to start core service [/rosout]←[0m←[31mThe traceback for the exception was written to the log file←[0m[master] killing on exit

I look in the path C:\opt\ros\melodic\x64\lib\rosout, but this folder is empty (Actually there should be a rosout.exe in there). Could it be that something went wrong with my installation or you can somehow post-install this rosout.exe into this folder.

I am glad about answers

Nils
