     <h3>Step B: Extract</h3>
     <p>
       Extract the zip file you just downloaded to <tt>C:\MinGW</tt> .  I would use that exact location; I will be referring to
-      that location in the rest of the instructions.  After extraction, double check that there exists a file
+      that location in the rest of the instructions.  <font color="#ff0000">If you choose a different location, make sure that there is no space in
+      the path.</font>  After extraction, double check that there exists a file
       <tt>C:\MinGW\bin\mingw-get.exe</tt> .  If such a file does not exist, you extracted at an incorrect level or you downloaded
       the wrong zip archive.
