I too am having trouble with installing add-ons. I am trying to install the xenporta plugin. I downloaded it and unzipped it on my desktop. There is 2 folders in it: JP and Library. There is also a file named DONATIONS. From what I am understanding, this is what I have to do:
1. I have to take the contents of whats inside of the library and place it in this directory: /www/library
2. Next, I have to locate and remember where the file: addon-EWRporta is located (which is in /www/library/EWRporta/addon-EWRporta.xml)
3. Finally, I have to goto my Admin CP and click on Add-on, click on install New Add-on.
4. on the Install New Add-on page, I have to choose Install file from server and type: /www/library/EWRporta/addon-EWRporta.xml
Please correct me if I am wrong.
Question: what do I do with the rest of the contents that I have downloaded?
