To indicate where the GDAL binary directory exists if you do not do the default installation, you must directly edit the MICRODEM.INI file. The default location at 'C:\OSGeo4W64\bin' will be much less bother, and if you want another location, you are expected to do your own troubleshooting.

MICRODEM creates a command line or batch file  to use GDAL.  This command will be written to the debug log.  If there are problems, you can copy that command into a CMD window, run it, and see the error messages to try to debug the process.
