Keeping up to date

To make sure you are using the latest version of the software you should do the following.

1) Check the version number of the version you are currently using. The full version number is in a format like ver1.0.1.1 and can be found on the About screen available from the Help Menu.

2) Users should then visit http://www.flv-converter.net/download.htm and check the latest version available. If there is a new version available download it, make sure 4U FLV Converter isn't running, then install it - into the same folder as that in which your original version was installed. The 4U FLV Converter installer will attempt to find this folder automatically - you should confirm that it has the correct one before applying the update.
