deployment - Visual Studio Setup Project that upgrades an existing app -


is possible make setup project in visual studio *does not install* upgrades app exists on user's disk ? example: user has version 1.1 of product , want send em setup / installer upgrades 1.1 1.2 ?

regards, madseb

sure. first create installer new version.

if old version installed msi package:

  • find old msi upgradecode
  • after building new msi open orca
  • go "property" table , set upgradecode of old msi
  • this way new package should automatically uninstall old one

if installed custom package:

  • in new package add custom action removes old version (for example launches old version uninstaller or manually deletes application resources)
  • make sure custom action runs before "installinitialize" action in "installexecutesequence" table (you can edit action sequence orca)
