Installation on Joomla 3

Hi, I've renewed the download for my Awocoupon Pro license.

I'm upgrading my site to Joomla 3+Virtuemart 3

Downloaded and unzipped: com_awocoupon-PRO-2.5.9.2.zip

When I try to install downloaded component after unzipping it I'm getting this message:

Looks like you might need to manually upgrade.  What version are you upgrading from?

No, it's a new site, I'm migrating my old site from joomla 1.5 to a new joomla 3 + virtuemart 3, Awocoupon is not installed.

Ok, so awocoupon is not currently installed?  If that is the case, can you look in the database and delete any tables starting with #__awocoupon.  Then install again.

Got it, for some reason first installation attemp left the component partially installed, the succesfull attemp was this way:

- Changed PHP version from 7.x to 5.6

- Removed all awocoupon* tables

- Removed manually the awocoupon entry in extensions table.

- Removed all folders

- Reinstalled component uploading the com_awocoupon-PRO-2.5.9.2.zip file.

- Back to php 7 version.

Thank you.
