Bug #72533	Unsuccessful installation [Windows] using community web installer

Status:	Closed	Impact on me:	None
Category:	MySQL for Windows: Installer	Severity:	S3 (Non-critical)
Version:	5.7.4 64-Bit, Installer: 5.6.17.0	OS:	Windows (7 (64-Bit))
Assigned to:		CPU Architecture:	Any

Description:
In a Win7 (64-Bit) VM, I tried to install version 5.7.4 of the MySQL community server using mysql-installer-web-community-5.6.17.0.msi.
After installing the server and configuring the service, the MySQL57 service does not start. During 'Initial Configuration', MySQL installer displays the line 'mysql-server-5.7-winx64:43 - Attempting to start service.' in the details section and stucks. Meanwhile, MySQL Notifier recognises a new server instance and reports 1) Service MySQL57 changed status from Stopped to StartPending...' and 2) Service MySQL57 changed status from StartPending to Stopped...', a few moments later.
Attempts to start the service (via MySQL Notifier or via the Windows service utility) do not succeed.
The Error log indicates an
   [ERROR] unknown variable 'innodb_additional_mem_pool_size=4M'
exception just before the line
   [ERROR] Aborting.
Indeed, after commenting the option in the 'my.ini' file, the service starts.

How to repeat:
Download community web Installer and run it to install Server version 5.7.4.
Accept default configuration, enter a root pw, and keep hitting 'Enter' (including the advanced options tab is optional to reproduce).

Suggested fix:
1) The quick solution: Comment the line
innodb_additional_mem_pool_size=4M
in the service's 'my.ini' file,
2) exclude the option from the 5.7.4 default config file or
3) un-unknow the variable to mysql ;)

Indeed, innodb_additional_mem_pool_size was deprecated in 5.6 and removed in 5.7.4. It shouldn't be in the default my.ini at all.wind

I'm getting the status same as described (service not starting) but don't see any line such as 'innodb_additional_mem_pool_size=4M' in my.ini.

I tested this using the latest MySQL Installer, I can't reproduce the problem about the deprecated variable anymore.
The variable may have been removed from the config file, just need a developer to confirm this in order to close the bug.

Verified, the variable innodb_additional_mem_pool_size does exist for my-template-5.6.ini but it was deprecated for the newer template my-template-5.7.ini and it no longer exists.

Fixed as of the upcoming MySQL Installer 1.4.17 release, and here's the changelog entry:

The innodb_additional_mem_pool_size option was removed from the default
my.ini templates, as it was deprecated in MySQL 5.6 and removed in MySQL
5.7.

Thank you for the bug report.
