For example, update configDirectoryRoot as follows: 
				  
 
				  <entry key="configDirectoryRoot">/home/user/tibcocfg</entry> 
				  
 
				  Note:  If TIBCO API Exchange Gateway is installed in a directory that has a configuration directory already set by another TIBCO product (for example, TIBCO Enterprise Message Service), you do not need to set the 
					 
configDirectoryRoot 
					 in the silent file
. 
					 In this case, the silent installer uses the value of 
					 
configDirectoryRoot 
					 as already set and ignores the value if set in the silent file.
