windows installer - misexec trying to update app that launched msiexec? -

-

we have updating app our product checks specific network location new msi, , if found, installs it. msi contains replacement update app well.

when msi runs update app screen disappears after 3 seconds can see in task manager still running 20 seconds or so.

we think installer tries kill using files in msi including update app , causes update app screen disappear. cannot prove if run update app somewhere else , fool thinking running product folder, not screen stay installation completes faster.

lots of products have updaters , presume run copy of update app temporary location avoid problem.

the issue face lot of our clients have highly constrained environments , there no certainty can copy or run exe location.

i had expected find some switches on msiexec deal issue, see none.

packaging update app separately 1 option, there else try first?
