Go to Extensions->Extension Manager-> Install
Find your package on your local computer using the "Browse" button. Then click "Upload and Install".
If this does work for some reason, for example: your host does not allow files over 2 megabytes or your connection is timing out, you can use FTP to put the unpacked file into your tmp directory (or other directory if you wish) and use the "Install from Directory" option.
A third option is to upload the file somewhere and point to it with the "Install from URL" option.
After installation/upgrading you should see a screen like this.
To update MyMuse with the latest file, follow the same procedure as installing. It is alwasy good practice to MAKE A BACKUP before major changes.
It will not touch your database and will simply overwrite old files with new ones. In case of emergency, have a backup.
MyMuse also uses Live Update. Go to Components->MyMuse to see the welcome screen. Live Update will inform you if there are updates available.
You must enter your username and password from the MyMuse site in the options screen to be able to receive the updates
To uninstall MyMuse, go to Extensions->Extension Manager-> Manage
Filter on the word MyMuse
You need ONLY SELECT MyMuse, the Administrator - Component. It will remove the component, all database tables, all MyMuse modules and plugins.
After uninstalling it will present a screen with information on what was done.
