Problem installing VM 3

[massimo]

Please I need an Help with the installation of VM3 on J2.5.28 - PHP 5.3.29 - MySql 5.5.40
I'm doing an installation but it gave me an error, and I got this (see the picture)
I can see the VM tables in the database and VM isn't installed .
This is the first time I have a problem like this.
I cannot uninstall the broken installation, I deleted the tables from the DB and the cache from Joomla, but the VM  "broken" menus are there.
Same with VM2.6.14-
Thank you for your help,
Massimo

ok Thank you, the _menu table now is clean, but I didn't understood what is the problem of the error in the installation

I just tried to install VM3.0.4 and this is the response (see image)
same as before, no way to work.

I have done the installation changing the admin language to english.
same as before, very strange message.

is this a clean install on a clean Joomla?  if so what joomla exactly

[massimo]

It is a clean install of VM 3.0.4 on joomla 2.5.28 - PHP 5.3.29 - MySql 5.5.40
Joomla is a gavick pro quickstart solution with already other components as: aicontactsafe, attachment, JCE, K2, SobiPro.

How can this be a clean install when you already have a Gavik quickstart there??  That's not clean!

clean is install Joomla - then VM - then the Gavik template -- see where you are then

after receiving help I would have thought a full explanation of how you fixed it would add to the sum of knowledge on here?

Or will we not see you till your next problem?

It was an old installation of virtuemart on joomla, I just delete language files and clean db table extensions, menu and assets and it works!
Thank you for your support.
