Download the Phoca Download component from the Phoca Download download site. You get a ZIP file. Login into your Joomla! administration site and follow these steps:
Extensions » Install/Uninstall (Extension Manager - since Joomla! 1.6) Now you are in Extensions Manager. You can:
- Upload Package File - select the Phoca Download component ZIP file from your disc and click on Upload File&Install.
- Install Directory - you can upload Phoca Download component ZIP file into your server directory and install it from this directory (see How to install large components with help of FTP in Joomla! 1.6 article)
- Install URL - you can install it from another URL.
Phoca Download should be uploaded and installed on your Joomla! site. The Installation procedure will create three folders ( images/phocadownload, phocadownload, phocadownload/userupload) on your server. If not (there may be possible problems with permissions), you must create it manually via FTP.
If you get errors in installation, try to see Installation Problem Solving article.
