问题
So I recently installed the WampServer a few months back, with a pre-installed mySQL 5.7.
But I wanted to take advantage of the NoSQL features that come with mySQL 8.
To update it, I downloaded the latest MySQL version, extracted the folder to the bin directory of wamp64. I then copied the wampserver.conf and my.ini files from the 5.7 folder and pasted it in to the 8 directory.
I ran on the cmd line the following prompt: mysqld.exe --initialize-insecure
I then edited the my.ini file and changed every instance of 5.7 to 8.0.
But now when I run wamp MySQL doesnt start and I get this error: error
Does anyone know what I did wrong or how I can fix this?

i found this at http://forum.wampserver.com/read.php?2,147674,147689 and it worked for me.
- Exit Wampserver
- Download MySQL version and extract to a folder, e.g. mysql-8.0.2-dmr-winx64
- Copy the contents of the folder to a new mysql subdirectory, e.g. wamp64/bin/mysql/mysql8.0.2
- Open a command windows (as an administrator) on wamp64/bin/mysql/mysql8.0.2/bin/
- Type : mysqld.exe --initialize-insecure --- This will create the right data folder
- Copy wampserver.conf from mysql5.7.14 to mysql8.0.2
- Copy my.ini from mysql5.7.14 to mysql8.0.2
- Edit mysql8.0.2/my.ini and replace all instances of mysql5.7.14 with mysql8.0.2 (then save)
- Run WampServer64 as administrator

Just go to following Wampserver repository and directly download and install the .exe of any of the component you want, it takes care of configuration.
For database up-gradation you have to import/export your databases manually.
Secondary repository of Wampserver files

As Gustavo said, it's working like that, but one additional information. If the wamp server is not starting correctly and stop at "orange" take a look at the log file.
Following error appeared:
"mysqld.exe: Error while setting value 'STRICT_ALL_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_ZERO_DATE,NO_ZERO_IN_DATE,NO_AUTO_CREATE_USER' to 'sql_mode'."
