Install Troubles - by: Danny Chau

Hi, Everybody:

I have two install troubles: I failed to install the "photos.zip" and "TCPDF.zip", they both show:

"Warning
JInstaller: :Install: Can't find XML setup file."

"Error
Unable to find install package"

How I can do? BTW, I just update the latest Joomla version 3.5.1.

Thank you.

Danny
