Jahia with MYSQL : Specified key was too long. Max key length is 1024

Hi,
I try to install Jahia on a Windows server with MySQL and I obtain the 
following error:
Jahia Configuration Wizard generates some error(s) :
Error : Specified key was too long; max key length is 1024 bytes

Here the answers which I gave:

I made some research and it seems to have a limitation in MySQL on this 
subject:

Mysql cannot have more than 1024 bytes in a key for a InnoDB table :
http://jira.undersunconsulting.com/browse/OFBIZ-66
http://bugs.mysql.com/bug.php?id=4541
http://dev.mysql.com/doc/connector/j/en/cj-character-sets.html

Here my configuration:
Jahia 4.04
Windows 2003
MySQL 4.1.9nt
J2SDK 1.4.2-7
mysql-connector-java 3.1.6
IE 6.0.3790.0

Is there any workaround to install Jahia in this configuration ?
Thanks.
