purchased plugin couldn't be installed

I purchased GProduct Plugin but the downloaded file doesn’t have any plugin, when I tried to install it in WordPress it fails.

Hi,

Please go to download page Downloads. You can download ‘Installable WordPress file only’ from there and install from wp-admin=>Plugins=>Add New.

If ‘Installable WordPress file only’ option not exist then try the following:
You have to install the plugin zip not the full download (All files & documentation) zip. Please unzip the main full download (All files & documentation) and then locate the installable plugin zip file within it. Luckily most developers clearly label their files, so it should be pretty easy to find. you have to install that plugin zip from wp-admin=>Plugins=>Add New.

Thanks
