Software update with MSI installer
-
Hi, in my attempts to create an MSI installer (with WiX) I did run into a dead end and could need some help with the following scenario: - user downloads latest MSI from website and double clicks to install application - if not installed on PC, then do fresh install - if already installed and newer version, then do software update and replace files Nothing special I guess. Such an software update requires no registry changes, not changing/removing installed components, just updating already installed exe/dlls in the installation folder. I followed the instructions at (http://www.tramontana.co.hu/wix/lesson4.php) and as far as I understand a '
minor upgrade' is not possible. Quote from the WiX tutorial: For some strange reason, small updates and minor upgrades cannot be run simply by clicking on the .msi file—they give the error: "Another version of this product is already installed." We know, stupid... Anyway, you have to start it with the command: msiexec /i SampleUpgrade.msi REINSTALL=ALL REINSTALLMODE=vomus
Asking average user to use command line arguments is not really an option here or adding another file that launches the MSI (it's downloaded from a website)... I wonder what are my options? 1) Do you have to do a 'major upgrade' for every application release or are there any other tricks? 2) What have they been thinking? Thanks in advance, Moak -

Thanks in advance, MoakA 'major upgrade' is the standard software update mechanism for MSI files, it works now.... was a bit tricky to find information. :)
