Why can't open MT4 software in WIN98 system

 
I installed and uninstalled MT4 software several times. I can't open the Mt4 software after install, the software didn't any active, I checked my WIN98 process that I didn't find MT4 in process after opening the software.

Why?
 
It must be Windows98 Second Edition
 
How to solve this problem for Windows98 Second Edition ?

Is MT4 not support to Windows98 Second Edition ?
