There are three types of upgrades: Small update Minor upgrade Major upgrade
If you use the minor upgrades your launcher needs to be able to decide if the previous version exists on the machine or not. If it does exist a special command line is needed to install the new over the old. If you author a major upgrade no special launcher is needed. You can also pick between different scheduling options. One of the options will only update files that change and then remove old files. See this link for a detailed explanation. http://blogs.technet.com/alexshev/archive/2008/02/15/from-msi-to-wix-part-8-major-upgrade.aspx As for the registry key issue, it can be a little complicated. The following article is easy to read and the concepts explained can be used for registry keys that are created during the install. http://www.codeproject.com/KB/system/msi_upgrade_uninstall.aspx?fid=221266&df=90&mpp=25&noise=3&sort=Position&view=Quick&select=1828686 -----Original Message----- From: Chris Lord [mailto:chris.l...@atterotech.com] Sent: Thursday, December 11, 2008 1:19 PM To: wix-users Subject: [WiX-users] Simple upgrade. Hi all, I am somewhat perplexed with the whole upgrade path. I have read and re-read the Wix docs, the MSDN data, months of WiX posts relating to upgrading and anything else I can get my hands on. The more I read, the more confusing it gets and the less I seem to understand. I am hoping someone can shed some light. My install contains the main .EXE application and a few support files of which all but one do not change. When we create a new version, generally all that changes is the .EXE and once in a while, the support file. What I'd like to achieve is this..... I want to supply the end user with an MSI. When run, it detects if a previous version has been installed. If it hasn't then it go ahead and installs everything. If a previous install is found, it should just update the EXE file and maybe the support file as needed. >From what I have read, it appears that an upgrade requires uninstallation of the original software but there are settings set up by the user in the registry which would also be removed. I'd like to save the user from the hassle of having to setup things up again. Is this possible and if so how?
