Use %PROGRAMDATA% instead of %LOCALAPPDATA% for deploying apps

[shiftkey]

From @matteomigliore:

is it possible to use %ProgramData% instead %LocalAppData%, we need a shared installation for all users

I know one of the things that @xpaulbettsx wanted at the start was to have these apps sandboxed per-user. Making "shared installs" an option will probably require some research and experimentation.

TODO:

• discuss how this fits with our initial goals of Shimmer

No UAC dialogs, which means.... ...installs to the local user account (i.e. under %LocalAppData%)

@xpaulbettsx I don't understand what do you mean :). Is it possible to use %ProgramData% to have no UAC and a shared install, no?

Note he's referring to the All Users profile and not Program Files.

Can you install to that without UAC? Good question. Probably not as it would mean one user could affect another without admin privileges and that would be bad.

That's what I suspect. Any and all evidence to the contrary is welcome though...

[matteomigliore]

@Haacked so what do you suggest to allow an installation without UAC in a shared folder for all users?

[anaisbetts]

%ProgramData% isn't ACLed to allow standard users to create directories:

I hate to say it, but this almost certainly isn't possible - either you're writing to a location that anyone can change (so it's insecure), or you need UAC.

While I certainly would welcome a proposal (i.e. the "How" part) to allow per-machine installs, Shimmer has always been designed around per-user installs. If you really really need per-machine, this might not be the right tool for you

[matteomigliore]

Is not a big problem, is just to avoid to install the application (and update) for each Windows user. But probably is better to use %AppData% for everything, binaries and data, as Dropbox for example, thanks to your observations I know that is the right direction.
