FileZilla keeps asking me to install new version even though new version has been installed

[civres]

When I open FileZilla, I am prompted to install version 3.13.0. I install it. But each time I launch Filezilla for a new use, I'm prompted to install the version I have already installed.

Here's the message:

3.13.0 (2015-08-15)

+ Display home directory instead of root directory if the last used directory does not exist
+ Larger initial size of main window if there is no stored size
+ Slightly increased size of page selection box in settings dialog

• Fix assertion in directory listing parser
• Fix drag&drop of remote files which broke in 3.13.0-rc1

3.13.0-rc2 (2015-08-10)

• Updated SFTP components from PuTTY
• Official binaries now link against GnuTLS 3.4.4
• Official binaries now link against SQLite 3.8.11.1

3.13.0-rc1 (2015-08-06)

+ For SFTP servers the private key file to use can now be specified in the Site Manager
+ The contents of each queue tab can now be exported through the context menu
+ MSW: The installer now registers the App Path so that FileZilla is recognized in the Win+R dialog
+ FileZilla now uses pugixml instead of TinyXML to parse and create XML files
+ Several performance improvements
+ Code cleanup and modernization, building FileZilla now requires a C++14 compiler

• Fixed an assert loading sitemanager.xml created by an old version
• If password saving is disabled, specifying a password on the command-line no longer leads to extraneous password prompts when transferring files
• If deleting remote directories via the directory tree, navigate out of the directory tree that is to be deleted

This can happen if you have multiple versions installed and keep opening an old version.

Please remove all superfluous copies of FileZilla.
