<cfset LOCAL.cmd = expandPath('..\library\gm.exe') />
<cfset LOCAL.args = "convert image1.jpg image2.jpg" />

<cfexecute variable="gm" errorVariable="error"
 name="#LOCAL.cmd#" 
 timeout="10" 
 arguments="#local.args#" />

<cfdump var="#gm#" />

This code always results in an empty string in gm. No matter how I execute gm with or without parameters. Other examples work fine like running cmd.exe or netstat.exe as is in the CFDocs example. I get no errors thrown or warnings in errorVariable, it simply does nothing.
