If you already have Elasto Mania version 1.0, 1.1 or 1.11, you only need to download a relatively
small executable file to upgrade to version 1.11a (this version has some bug
fixes over the previous versions).
The new executable file is zip compressed, so you need an uncompressing utility to get its content. For this task you can download WinZip for example www.winzip.com. Better yet, you should download Windows Commander from www.ghisler.com (it is a very good utility and can handle zip files also with ease).
After the uncompression you should replace your Elma.exe of your game by the new executable file (your game is located by default in the C:\Program Files\ElastoMania folder).
Download files are 165K. To upgrade to version 1.11a:
Download executable if you already have shareware version 1.0, 1.1 or 1.11.
Download executable if you already have registered version 1.0, 1.1 or 1.11 (you cannot use this file to upgrade your shareware version of the game).
