mysql installer for 32 bit windows fails to update to the latest version of mysql workbench!!! (no replies)

Why???

I downloaded the mysql installer from the following page for 32 bit windows
https://dev.mysql.com/downloads/workbench/

Even though I have only mysql workbench 6.3 it refuses to update to the latest mysql 8.0
Why???
I have updated the catalog also but it won't install the latest mysql workbench.
Why this strange behavior???
