Web app installed on computer

A Question - is it possible to install a web app on clients computer without him having access to the source ? The client in question has difficult internet access.
Thanks

You mean the Xojo source or the web app executable once its compiled ?

You can NOT give him the Xojo source.
But if you install the app on their computer using an account they have full access to then you have a hard time stopping him from manipulating the executable - but they cant change the executable.

Hi Norman. What I mean is to install an executable version as if it were a desktop app.

If you compile it into a standalone web application and give them the executable, they can run it, but they can’t modify the source.
