Description:
mysqld does not start correctl ...
after doing a full install (first doing a complete uninstall) using a .msi installer. (mysql-installer-community-5.7.17.0.msi)

In the logfile I find the following:

2017-03-27T08:52:21.506236Z 0 [ERROR] Incorrect definition of table mysql.db: expected column 'User' at position 2 to have type char(32), found type char(16).
2017-03-27T08:52:21.506236Z 0 [ERROR] mysql.user has no `Event_priv` column at position 28
2017-03-27T08:52:21.506236Z 0 [ERROR] Event Scheduler: An error occurred when initializing system tables. Disabling the Event Scheduler.

Installing and then continue to run the server works fine, but after a full shutdown/startup of Windows (because of weekend) mysqld does not run. 

How to repeat:
Try to do a full install on a Windows 10 Pro 64 bit, (US version)

After a shutdown / startup mysqld is not working due to database definition error.

Hello Christian,

Thank you for the bug report.
I tried to reproduce the issue at my end using  mysql-installer-web-community-5.7.17.0.msi but not seeing any issues with services.
Could you please provide step by step (exact screenshot, stack trace etc. - please make it as private if you prefer) to confirm this issue at our end?

Thanks,
Chiranjeevi.

I have been thinking about this and have come to the conclusion that it is unlikely that installation fails. 

The problem is more likely in the import of a database that I do right after installing MySQL.

I will try to verify if I'm right in my conclusion.

Hi again

I have verified that the problem is not installation but an import of data. 
Data are imported is a dump from a client system. I did not realise that the original system was a different version of MySQL. The dump file states that it is:

-- MySQL dump 10.13  Distrib 5.5.49, for debian-linux-gnu (x86_64)
--
-- Host: localhost    Database: 
-- ------------------------------------------------------
-- Server version	5.5.49-0ubuntu0.14.04.1

My system is a Windows 10 64 bit, MySql 5.7.17. 

If I insist on doing the import - because I need to make some changes to the database and need to test on a Production like database.

Do I need to install the same MySQL version on my development PC or can I make the import run on a newer MySQL f.ex. by removing the section that cause the problem.

The section that cause the problem is

DROP TABLE IF EXISTS `db`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `db` (
  `Host` char(60) COLLATE utf8_bin NOT NULL DEFAULT '',
  `Db` char(64) COLLATE utf8_bin NOT NULL DEFAULT '',
