I had the same problem and solved it. I'm using 64-bit Windows 7 with 64-bit Java. Setting the compile target in the Configuration Manager to 'x64' solved it.

Answer 4

I also ran into the same problem and found my solution. It might help you too.

1. Set the PATH variable. I don't know if this step is required or not, but i just added the path to java.exe in TEMP variable.
2. At command prompt changed the current directory to java.exe parent directory.
3. Now ran to command which i required. If some file is been referenced in the command then i put the complete path.

Hope it helps you.

Answer 5

I don't know if this will help anyone else that is viewing this post but when i had this problem it was because I was running a x64 machine and the java.exe was installed to the ProgramFiles(x86) folder. I simply added the path to the exe to the 'PATH' environment variable and then it fired up just fine.

Hope this helps someone.
