I'm trying to install the k2 but is getting error

Table 'lnqizjqj_paid.zkosd_k2_categories' doesn't exist SQL=SHOW FULL COLUMNS FROM `zkosd_k2_categories`

I fixed the table following this

and then, next error
Table 'lnqizjqj_paid.zkosd_k2_items' doesn't exist SQL=SHOW FULL COLUMNS FROM `zkosd_k2_items`

What is wrong?
Where is the problem?

Thank you

Uninstall K2.
Manually drop its database tables.

Cleanup (delete the contents but keep index.html) of the tmp file and try installing again.

Thank you, it worked!

You 're welcome :)

Deleting all files in /tmp folder also worked for me. However strange as I never tried to install K2 before on this new Joomla v3 instance.

Could be a conflict with leftovers from a Joomla! update or an extension installation.
It is considered a good practise to cleanup the /tmp folder after such an action.
