  Hi Marius,
 You need to make sure you have internet access. If you are behind a proxy
 We have internet access and we are not using a proxy (afaik). However
 although we /can/ reach the internet, our hosts are not reachable /from/
 the internet (NAT) but I don't assume that's required.
 Also I cannot find any "connection refused" exceptions in tomcat/logs/*.
 . It may also happen that the 
extensions.xwiki.org is down at the moment
  you try to run the Distribution Wizard. You
should try again a bit later.
 
 I'm trying since over 24 hours now, at least 10-15 times. I cannot
 imagine, that 
extensions.xwiki.org was down all the time. It is reachable
 by https right now and I still experience the error message
 
 
  Is there a way to manually install this extension?
 
You can download the XAR file from
http://enterprise.xwiki.org/xwiki/bin/view/Main/Download#HStable and follow
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationConcludingS…
from "Alternatively you can skip ..." . But it would be better to
understand the problem.
