uninstall mysql net connector 6.8.3 (no replies)

Hi folks,

I had a bad instalation of mysql net conector 6.8.3.
I try to install it again and it rolls back.
I try to instal previous version 6.7... and it says there is 6.8.3 installed.
I uninstall all mysql from my machine.
I clean register.
I remove all mysql references from machine.config.
And still cannot install or uninstall 6.8.3 or 6.7...

Please help me.

TIA
