Failed to uninstall self. Please uninstall manually.

While I appreciate what you are trying to do, indeed it is pre-sales. If I cannot get it working from the beginning then why would I even consider buying it?

Even clearing the cache doesn't work.Even starting afresh doesn't work. Could it be release of joomla dependent? What does a cryptic message like failed to install underneath a banner of in stallation successful mean?

That's not how this works. "You provide support THEN I subscribe" is not our business model. Presales is for presales questions regarding products, e.g. "Can CB Privacy protect the privacy of a single field or is it profile only?".

Unzip the package then within the extensions/packages/ folder install the zip there. I've no idea why package installer is not working for you, but we do not test Joomla 2.5 (it has been EOL since 2014.. you really should consider upgrading to 3.x) so I've no idea if it's a Joomla related problem.
