Problem with installation folder of application by Visual Studio 2019

Question

I made an application called ApplName and it is version 1.0.0.0

install it and place it in folder "C:/Users/%USERNAME%/appdata/Local/Apps/2.0/folder/folder/applnamefolder"

I upgrade the same application with the name ApplName and it is now version 1.0.0.1

install it and place it in folder "C:/Users/%USERNAME%/appdata/Local/Apps/2.0/folder/folder/applnamefolder1"

Why was the installation done in a different folder from the previous one and not overwriting the previous application?

Why the installation did not take place in the known folder "C:/Program Files/Applname"?

How can I change the installation folder and place it in the folder "C:/Program Files/Applname"?

Hi @Apostolos Doudakmanis , 

Welcome to Microsoft Q&A! 

What is your application? How did you upgrade it? 

If it is a setup project, please ensure that “RemovePreviousVersion" in the Setup Deployment Project Properties window is set to True.

You can change the default install path by right-clicking on Application Folder in File System > DefaultLocation. 

Sincerely,

Anna

is a VB.net application from Visual Studio 2019 - ClickOne enabled

by publishing you create a new version of the app when running the app, on startup it looks for an upgrade and if it finds one,

it upgrades then it creates a new folder with the new version of the app, - it doesn't overwrite the old app.

So I have 2 folders with 2 different versions and 2 different desktop icons
