C:\Program Files (x86)\AMD APP\bin\x86_64;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files\Java\jre1.8.0_25\bin
and still isn't working. My program files in on C: itself. Kindly help. Thank You.
