Hello I can't install the B2J Contact. I get the above error:

JInstaller: :Install: Can't find XML setup file.
Copy failed: /tmp/source/site/index.html to /components/com_b2jcontact/index.html

JInstaller: :Install: Failed to copy file /tmp/source/site/index.html to components/com_b2jcontact/index.html
