I used to exploitate E-Dragon online tools in my QSAR research years ago.

But now it doesn't work.
1. Probably the problem is with Java. I enabled Javascript in the browser, but it didn't help.
Probably, Java version should be old enough. I downloaded Java version 1.4.2, but it didn't help. Now I have two versions of java installed: 1.4 and 1.8. I'm not sure which version works along with the internet browser.
2. I enabled the pop-up windows, so it's probably not a problem.
3. In most contemporary browsers Java is disabled. For example, starting with Chrome version 42, Chrome has disabled the standard way in which browsers support plugins.
I'm trying to start Dragon in Internet Explorer, Safari and Mozilla version 50, but it still doesn't work. For example, IE just freezes while Safari and Mozilla give similar error message: "Your browser is completely ignoring the tag! ".
Please, help!
I think that VCCLAB is no more mantained. Anyway you can use the "Calculate Descriptors" feature on OCHEM (https://ochem.eu/home/show.do).
You can calculate a lot of descriptors, among them you can find alvaDesc descriptors https://bit.ly/2Rv46Cf).
