Core not installed?

Hi..

I checked the installation check after updating to 1.4.2 and it says my core is not installed and it will not work. Any advice?

Not Installed Core (Required) File: www/administrator/components/com_virtuemart/classes/ps_coupon.php
Required. This injection is the core of AwoCoupon Pro and no coupon code from within AwoCoupon will work without it.

It does not allow me to install.

I am also having an issue when a product is purchased in VM and linked to AWO it does not send the coupon via email, VM sends its mail and order summary just fine. Is this related?

Hello,

You will have to update the file manually then. Please take a look in your download at user_guide.html, the troubleshooting section. It gives step by step on how to do this.
