Update controls in Custom Toolbox Controls

I created a project "Windows Forms Toolbox Control" and added some custom controls:

When installing .vsix file, everything works fine and the tool box and its controls are available for use. After you add a custom control on another project, I could see the reference to the dll and its respective path.

Then I had to implement a new property to one of the controls and did the update of the extension via a private gallery of the company. To my surprise, the extension has been updated, the controls available again correctly, but in another directory.

Install:

After update:

With this, the project that was using one of the controls had broken the design, because the dll lost the reference:

What can I do so that both the installation and upgrading are the same directory?

ps: Researched install .vsix with msi, but got no example.
