DP ROOT.exe is not a valid wind32 application

Hey guyz, I am trying to install the V2 DP ROOT tool so I can root my LG G3 but I cannot install it on my x86 Windows XP machine. I get the "DP ROOT.exe is not a valid win32 application" error. Any ideas why this is happening and how could it be fixed.

P.S. I have been searching through google for 2 hours now, so just ignore giving me threads from google... or at least threads from the first 10 pages, tried them all so far.
