Need quotes around a couple more paths in jmeter.bat (similar to bug 39677), if .%JM_LAUNCH% == . set JM_LAUNCH=java.exe should be if ".%JM_LAUNCH%" == "." set JM_LAUNCH=java.exe and if .%JMETER_BIN% == . set JMETER_BIN=%~dp0 should be if ".%JMETER_BIN%" == "." set JMETER_BIN=%~dp0 Wouldn't so much of a problem except that Windows put a space in the middle of the name for the default program folder....
