windows - Update per machine instance of application in multiuser enviroment -

-

how installer/windows/wix handles following situation i.e. assume more 1 user working on machine instance of program installed option per machine. 1 of user proceeds upgrade of applications.

how installation proceed , how handled on other user profiles? additional changes in wix project has made allow installer proceed such update?

checked instance of program not closed on other user profile , user can still work program.

if per-machine product install there 1 instance of installed product, user appropriate privilege can choose upgrade when choose. there may multiple copies of app running different users that's not relevant update because there still 1 product update. person doing update owns current desktop's interactive view, see ui notifications - other users won't.

the behavior multiple users depends on msi design , app itself. example, if msi installs 1 template copy of data file app copies , modifies each user profile file location msi upgrade isn't involved because won't replace of of data files created app.

if you're referring multiple copies of app running, won't see issues if update doesn't affect files in use, yes, users can keep on working. it's dynamic , depends on file replacement rules, if in use , on.

in cases windows can keep app running though it's being uninstalled or replaced. makes private copies of binaries removed @ next reboot or when program finishes. it's not predictable happen.

unfortuanately question rather vague, answer may vague. if have specific scenario, , if update patch or major upgrade, , explain user profiles you're referring answers can more specific.
