I made the msi package to allow the user to choose installation directory for the application.

I want the user to only download the application where it doesn't need read write permissions from the user, like %APP_DATA%/Roaming/my_app_example_name.
The reason being that the application has a self update mechanism and updates itself when it detects a new version on the server. The update itself doesn't use an msi launcher, it just downloads the new version of the app from the server using a http request, and replaces the old files.

For example, in the popular game

Here, you can see that the default installtation directory is the Appdata folder

If i change the installation directory to ProgramFiles, and try to install, I get this error :

It effectively blocks installation to the directory simply because it doesn't have permissions to create a folder from the installer itself, there.

I would like to implement the same mechanism, or something similar, because I think this is a very elegant solution to my problem. So any ideas on how to do this?

(By the way, I'm using jpackage to create the msi launchers)

CodePudding user response：

You can use --win-per-user-install option with jpackage.

On Windows, the default is c:\Program Files\application-name; if the --win-per-user-install option is used, the default is C:\Users\user-name\AppData\Local\application-name
