There is no link to download the virtual appliance, when you click the link, you go to http://www.vmware.com/appliances/directory/342 which brings up the page for the appliance with very good details about it, just no way to download it from there. Please let me know when this is fixed, I would like to evaluate it.
Yes, I have a vmware account and did login to download the appliance. But there is no link to download it. Did it display a link for you? I see links for documents for admin, reseller, etc and the default username/password to use, that is it.
This appliance is several years old and deprecated. It can not be updated with recent ispconfig versions so you should not use it anyway.
