cannot install spambotcheck

Hello Sjaak,

thanks for that information.
If it was uninstalled before the update that is, what I would think should work.

Sadly I'm a bit at a loss with your problem.
I can offer you to take a look at the #__extensions table if you like.
Please export the #__extensions table then from your database and mail it to me (contact@vi-solutions.de).
I could take a look, if I find a reason for your problem.

Regards,
Aicha

Just to finish this post.

After some research it turned out that, due to a bad file order in the download section and a simple overlooking, it was not the plugin but a language package, that was installed.
After finding the plugin installation package, everything was ok.
