In this case, you might want to consider authoring a patch which targets both product's MSIs? (instead of trying to use a single MSI to update [what are essentially] multiple SKUs)

Sorry for the misunderstanding. If the user first installs the initial installer WITH JRE, it has to be installed of course. Otherwise he would have been able to download the smaller installer package without JRE. If we now release a bug fix, he should be able to install the installer package without the JRE to keep his already installed JRE (and to safe us band-width). First installation: - Always install the JRE if it is contained in the installer package. Update installation on top: - If installing the bundle with JRE, the previously installed JRE should be replaced. - If installing the bundle without JRE, the previously installed JRE should be kept. Uninstallation: - The JRE should be uninstalled if it was installed. -- Tom John Nannenga wrote: > Ok, so these are essentially components within your installation. > > In theory then, one way to accomplish this is to create a 'hidden' feature > (perhaps called "JRE") within your application installation that shouldn't > install the JRE, and add the same ComponentGroupRef to that feature. > Condition the "JRE" feature to only be installed when your upgrade property > is present.
