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? Thanks Chris Lord Attero Tech LLC.
