Description:
MySQL 5.6.14 installed from mysql-installer-community-5.6.14.0.msi on Windows 7 Professional SP1.  
When the server was started and the error log was checked, the second line read, 
2013-09-24 09:40:10 4000 [Warning] option 'innodb-autoextend-increment': unsigned value 67108864 adjusted to 1000 

The options file my.ini was checked and the option was found set to:

# The increment size (in MB) for extending the size of an auto-extend InnoDB system tablespace file when it becomes full.
innodb_autoextend_increment=64M

When the option was changed to remove the trailing "M" at the end, the error was corrected:

# The increment size (in MB) for extending the size of an auto-extend InnoDB system tablespace file when it becomes full.
innodb_autoextend_increment=64

How to repeat:
Install MySQL and check error file.

Suggested fix:
Make corrections to the installation program to create this option in my.ini without the trailing "M".

Fixed as of the upcoming MySQL Installer for Windows release, and here's the changelog entry:

The "my.ini" template for MySQL Server 5.6/5.7 were updated to use an
undecorated value for the "innodb_autoextend_increment" option, such as
"64" instead of the previous "64M".

Thank you for the bug report.
