I can't uninstall VM and VM AIO

[cobra-arbok]

It was installed VM & VM AIO over a year ago, but only a basic initial installation was done..
The project was then canceled and so VM and VM AIO should be removed but I still get the error:

Code Select Expand

Package Uninstall: Missing manifest file.
Error uninstalling package.

Where can I find a procedure to do this?

VirtueMart version: 4.2.18 11050

In general, if you uninstall Virtuemart, the tables willl be kept. The reason is, that we had users, which had the idea to "reinstall" virtuemart. Which means to uninstall and install again. But we, or I as developer always use the pure update to fix an error. Which means that we just use the installer and install it over the old installation.
So the normal joomla deinstallation removed all tables, which lead sometimes to heavy data losses. Therefore you should first use the uninstall option within VirtueMart, among Tools.

But your problem is different. We have the core and the aio, and a package which combines both. Maybe your installation just shows the old package.... so you just need to remove the old tables yourself and then you can also remove the entry of the package (in the extensions table)
