Marinuzzi [mailto:nu...@hypack.com] Sent: Wednesday, July 22, 2009 10:12 AM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Upgrading... Hello, I used WIX to create an installer for our last release of our software. I was using NSIS prior to that, but we had customers who wanted to be to implement installs over a network, so we switched. So, we are at a point where I have to do another release, and I want to be able to 1) Install new if the older version does not exist, and 2) uninstall the older version before installing if it does exist. I have looked at Upgrade and Upgrade codes, etc., but cannot grasp what exactly I have to do. All the attempts I have tried have either given me the "already installed" error, or installed separate keeping the older version in the programs listing. Any suggestions on a good source to understand this? I have tried the documentation here on the site, but can't seem to figure out if I need new GUIDs or use older ones, etc. Thank You, John ---------------------------------------------------------------------------- -- _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users ------------------------------------------------------------------------------ _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users
