MySQL Server 5.7 installation fails at "Writing configuration file" -

i'm trying install mysql server 5.7.7 on windows server 2008 machine. has failed several times , tried uninstalling whole thing , try installation again. tried installing 1 component @ time , worked components (workbench, connectors,..etc.) except mysql server itself.

i'm receiving error @ step "writing configuration file", log shows error details below:

beginning configuration step: writing configuration file not find part of path 'c:\programdata\mysql\mysql server 5.7\my.ini'. ended configuration step: writing configuration file 

i had same problem. solve it, created "mysql server 5.7" folder in "c:\programdata\mysql" clicked retry in installer

i've had bad experiences mysql installers in past. surprised it's not smart enough (or lazy?) create sub folders before trying write ini file.

hope helps!
