I download the binary to start ide but I got an error as reported in attached image,can anyone help me ?
I am not absolutely use but it looks like you have only installed a 64 Bit Java VM and you have installed a 32 Bit Eclipse. If you only hava a 64 Bit Java VM installed you have to install a 64 Bit Eclipse.
I had the same problem. As Martin mentioned it is a problem with 32/64bit Java VM.
The windows download of the openhab designer needs a 32-bit Java VM. So download and install the 32-bit VM and it will work.
