I am using Joomla 1.5.14. I have just tried uninstalling 2.54 and installing version 3.0. The result is a failed install. I had to reinstall version 2.54.

The error messages are:

"JInstaller::install: There is already a folder called

'/home/myaccount/public_html/plugins/content/jw_allvideos'. Please

initially check whether:
• the Extension is already installed
• the file names in the XML file are spelled correctly
• there are no XML files listed inside the extension.xml file
• all of the files (not including XML files) are correctly listed in
the extension.xml file and there are no duplicate entries
• there is an empty folder listed from a previous installation attempt

Install Plugin Error"

Any assistance gratefully received.

Update. I found the solution after re-reading the error message. Although the uninstallation of version 2.54 was reported as successful, the jw_allvideos folder had NOT been deleted by the uninstallation process. I used FTP to delete the jw_allvideos folder at:

'/home/myaccount/public_html/plugins/content/jw_allvideos'.

This allowed version 3.0 to be installed OK.

Hope this helps others.

Many thanks to the JoomlaWorks team for this upgrade.
