Hi!
I updated a website from Joomla 3.9.x to 4.1 and now when I try to uninstall Akeeba 7.0.2 it shows me following error:
You need Joomla! 4.0.99 or earlier to install this extension
Extension Uninstall: Custom install routine failure. info Error uninstalling component. How can I uninstall it? thanks, Elisa
Hello Elisa!
simply update to the latest version of Akeeba Backup, it's the only one compatible with Joomla 4.1, there's no need to uninstall. If you really have to uninstall it, first update and then uninstall it.
All other versions have a check to not run under Joomla 4.1 since they were not tested against it and there could be issues.

Hi Elisa!
Something does not sound right here.
You cannot upgrade from Joomla 3.9 to 4. You would have to first upgrade to Joomla 3.10.
Moreover, Akeeba Backup 7.0.2 was released well over 2 years ago. It was never compatible with Joomla 4 stable, it was only compatible with some early alphas and betas.
So, first, verify your versions.
If the versions are correct we'll have to do it the Hard Way™.
First, delete the files:
These are Joomla's cached copies of the installation scripts for the old Akeeba Backup package, the old Akeeba Backup component and the defunct installer plugin which will be removed from your site. These prevent the uninstallation.
Uninstall the Akeeba Backup package, version 7.0.2.
Delete the tables:
They are left behind because we removed the installation script from the component, therefore it doesn't know which tables to drop on extension uninstallation.
Uninstall FOF 3.
Uninstall FEF.
Since we removed their installation scripts they will uninstall without checking for dependencies or the Joomla version.
Finally, install Akeeba Backup 9 again, twice in a row, without uninstalling before or in between. This makes sure that any errant plugin removal will be undone and AB9 will be back in working order.

Hi Nic!
thank you, yes the versions I said before were right. I know it sounds a bit odd. Someone approached me with his 3.9.x and asked me to upgrade, I simply forgot to update to 3.10 first and "Joomla Next" offered me directly the step to 4.1 - Now I know why my backend seemed to be broken in the first moment after that.
I clicked then on reinstall Core Files and everything was ok. Just not the two Versions of Akeeba :-D
So I will follow your recommendations to remove it from the Database and the folders and reinstall it. Thanks for the hints.

Holly cow, Joomla upgraded from 3.9 to 4.1?! 😵 I would file that as an issue in the Joomla issue tracker. This is not a supported upgrade path. It should be forbidden.
Please let me know if the Very Hard Way™ method works. It's based on my notes about the untested scenario of ‘what if something impossible happens’. We are quite used to dealing with “impossible” issues as it turns out...

I think I will redo the whole process to reproduce so I can file it as an issue on GH :-) But yes - I am quite sure it was an upgrade from 3.9 to 4.1 on the highway :-D
The Very Hard Way™ Method worked very good thank you. I identified two other script.php I needed to delete, the backup on update in plugins and the path for administrator/manifests/cache/akeeba/script.akeeba.php was administrator/manifests/cache/packages/akeeba/script.akeeba.php
Thanks again for your exzellent, fast and professional support!
Oops! Thanks for spotting my typo!
Have a great weekend :)

I just mentioned it in case you need to recommend the method again :-) Have a great weekend too and thanks for your help!
