Description:
Hi,
I installed the MySQL server using mysql-installer-community-8.0.16.0.msi.

Afterwards, looking at my PATH env var, the only thing in it is C:\Program Files\MySQL\MySQL Shell 8.0\bin\

It looks like the MySQL installer deleted everything else, which isn't cool.

How to repeat:
Install the MySQL server using mysql-installer-community-8.0.16.0.msi.
I selected a custom install.

Suggested fix:
Don't delete the existing path vars, append to the PATH instead.

Thank you for the bug report. I couldn't repeat this issue on Windows 10 Pro, please provide the exactly Windows OS you use, the exactly step by step of the install process you applied. Thanks in advance.

Hi, I faced this same issue, MySQL installer replaces the whole PATH env var string with "C:\Program Files\MySQL\MySQL Shell 8.0\bin\".

OS: Windows 10 1809 17763.503 (PT-BR)

using the offline MySQL Community installer 8.0.16.0 from
https://cdn.mysql.com//Downloads/MySQLInstaller/mysql-installer-community-8.0.16.0.msi

The installer log ending part has this:
DoStep
Action 12:22:39: WriteEnvironmentStrings. Updating environment strings
Step: 13200
Position: 103299872
Name: PATH, Value: C:\Program Files\MySQL\MySQL Shell 8.0\bin\, Action 1

information that was originally requested, please do so and change
the status of the bug back to "Open".

Verified this behavior in MySQL Shell 8.0.16.

To reproduce it simply complete a Shell installation either via the MySQL Installer or by directly executing MySQL Shell's MSI.

Once the installation completes the PATH User Environment Variable only retains the data related to MySQL Shell.

Just installed mysql-installer-community-8.0.17.0.1, to upgrade my previous installation.

It once again deleted the contents of my PATH variable.  Luckily I was smart enough to back it up this time before i Ran the installer.

Come on guys, sort your sh*t out.

Changelog entry added for MySQL Shell 8.0.18:

Due to a bug introduced by a change in MySQL Shell 8.0.16, the MSI file that is used by Windows Installer to install MySQL Shell overwrote the Windows PATH environment variable with the path to the application binary (mysqlsh), removing any other paths present. The issue has now been fixed.
