To install the codec mp3 Lame from Elecard:


1) Download the file "lame.ax"  on the page of freewares from Elecard (http://www.elecard.com/download/#freeware) 
under the title "MPEG Layer III Audio Encoder". 

2) Unzip into the same folder as for lame.ax, the files reg.bat and unreg.bat here attached.

3) To install lame.ax, double-click on reg.bat

4) To uninstall it, double-click on unreg.bat

If it doesn't work, it's perhaps because the file regsvr32.exe has not been found in the folder c:\windows\system32

Search your computer to find out in which folder it is located and fix yourself with a text editor the path to this file  in the two files reg.bat and unreg.bat
