Well, most of the people usually like to use the exchange in a web instead of a client because its way too easy to access rather than a client. I hope they made a web version.
Indeed, they had. The web version is available at
https://client.wavesplatform.com and needs no installation. When enter the link it will ask you if you want to download desktop app or continue with web, Click on the second option and you are ready to go.
