Why is win10 not asking to remove another version of the same program and the same started source code but different copies?

After publishing to hard drive in a folder and changing version to newer each time:

Before the Windows Ten updates being installed, when I was about to install a newer version of my published to hard drive WinFormsApp, it was telling me something like : "There's the same program installed in another location", and I have to remove that, this made sure the user doesn't install the same program in 2 different versions and he had to uninstall the old version to install the new.

Maybe because WinTen updates have been installed now it can install 2 (maybe more) versions of the same program (2 versions that started from the same solution).

What I have tried:

I tried Visual Studio 2019 first then VS 2017.

Not enough information. How are you installing the app? Click-Once, Install Shield, etc?

I don't know much, I just click "Build->Publish SpeakTextApp", and choose a location on my hard drive like "D:\SpeakTextV7.9\".

Then double click Setup.exe and a window called "Application install - security warning" opens with a button called "Install" and it gets installed in one click then.

Then you need to look at why the installer that you are using is performing differently. I suggest that you have missed a setting in the process of publishing the app rather than the version of Windows that you are installing on.

What do you mean by "missed a setting"?

Graeme_Grant 18-Jan-19 23:32pm

Don't just use default settings for the publish process, check the settings before publishing.

I will check, anyway it used to work with the default settings. EDIT: Nothing found.

Obviously, something has changed, that is why you check and never assume or jump to conclusions.

I'm not familiar with how it was before the update and tried VS 19 and 17, I used the default settings and have not much info on publishing or installing.

Could the "program-id" or something have changed by an act of copying or publishing or changing something in the source code?

Win 10 uses a different "model" for apps versus Win 8, 7, etc. (unless you're "side loading").

You can't assume that what "installed" previously works the same in Win 10 (like "publishing").
