<p class="MsoNormal">I followed your code and found that initGRASS searches for libraries and binaries of GRASS in gisBase folder. If we address a folder that doesn't have the code it comes back with this error message: "The code execution cannot proceed because
libgrass_gis.7.4.1.dll was not found. Reinstalling the program may fix this problem." it gives the same error even if I copy that file into GISBase folder.<u></u><u></u></p>
