A few months ago I wrote about this error that appears when someone is trying to install a module, extension or template design for previous Joomla versions. It's not the single time when this warning appears when trying you're trying to install or upgrade something.

Let's take for example the following code:

<?xml version="1.0" encoding="UTF-8"?>
<extension type="module" version="3.0" method="install">
<name>Joomla SlideShow</name>
<creationDate>2013-11-15</creationDate>
<author>Supravirtual SRL</author>
<copyright>(C) 2013 webdesign-software-code-seo.com. This module is released under the GNU/GPL v2 License</copyright>
<authorEmail>This email address is being protected from spambots. You need JavaScript enabled to view it.</authorEmail>
<authorUrl>http://www.webdesign-software-code-seo.com</authorUrl>
<version>1.0</version>
<description>Joomla horizontal and vertical Slideshow</description>
<license>http://www.gnu.org/licenseses/gpl-2.0.html GNU/GPL</license>
<files>....

The  XML file continue with the rest of the necessary code for a module. The error what I am referring to appears when one is changing the "and" from description to "&". Everything else is OK, the code is OK, but you can't install or upgrade your Joomla extension as long as you are using & in the file.

Joomla 3 is out for more than a month now. If you already upgraded your existing Joomla (or made a clean install) to the latest version you might have had a little surprise when you tried to install a new package (component, module or plugin) or to update a new one.

Warning JInstaller: :Install: Cannot find Joomla XML setup file

The reason of this error message is simple: the XML file present uses the <install> tag in the xml file which was deprecated at the end of Joomla 1.5 (although still worked in 2.5) however this function has now been removed from Joomla 3.0, hence it can't find a function that works.

The solution: open the xml file used for installation for editing and modify the <install> tag with the  the <extension> tag. For example, the following code

<?xml version="1.0" encoding="utf-8"?>
<install type="component" version="1.6.0">

... installation code...

</install>

will become

<?xml version="1.0" encoding="utf-8"?>
<extension type="component" version="1.6.0">

... installation code...

</extension>

Then save the file and repack to a zip archive (the installation package) the extension.
