I've just installed version 18 on a windows 7 machine, but the IDE won't load at all. I get the splash screen and then nothing. It is a Windows 7 64bit install.
I've read the forums and FAQ's and the solution seems to be to remove the java directory (which i've done) and reinstall JRE 32bit.
Unfortunately, this is where i think my problem is because I run Processing on this machine too, and have spent quite a while getting it to work in 64bit mode as some of my sketches use massive amounts of memory. The process involved installing the 64bit JRE.
Can I get Arduino 18 to work with JRE 64bit?
P.S. my FTDI cable works fine :)
