That dialog usually means that the product code is already used by an already installed product.
In WiX v3, use a produ...@id value of "*" (and never set the packa...@id value to anything except "*" under any conceivable condition) The ProductCode will always be different, automatically generating major upgrades. If you are already doing that, generate a verbose log and see what is going on. <Wix ...> <?define UpgradeCode="your-upgrade-code-goes-here-once-set-don't-ever-change-it"?> <Product Id="*" UpgradeCode="$(var.UpgradeCode)"> <Package Id="*" .../> <Upgrade Id="$(var.UpgradeCode)"> <UpgradeVersion Maximum="$(var.BuildVersion)" Property="UPGRADING"/> </Upgrade> ... </Product> </Wix> candle -dBuildVersion=1.0.%BuildNum% mymsi.wxs light mymsi.wixobj Change the environment var BuildNum between builds to ever increasing integers, never larger than 32767 (due to a bug in one of the ICE tests). -----Original Message----- From: Dean Arnold [mailto:dean.arn...@paraccel.com] Sent: Thursday, January 28, 2010 3:22 PM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Example to create upgradeable install ? I've checked the How to, and the tutorial. I tried using the example in the tutorial. I generated guid's for all the appropriate bits, and tried to install the upgrade from the tutorial example, and in every case it throws up a dialog box to the effect "that is already installed, please use Add/Remove Programs". I've tried changing Product guids, package guids, version numbers...no luck. Can anyone share a set of simple WiX XML that actually is upgradeable ? With real guids, so I can see what (if any) of them change between versions ? Fwiw, this is on WinXP SP3, and I'm using the candle/light command line to build the installers (example command line syntax for the upgrade scripts would be helpful as well). (btw: is there a searchable archive of this list ? sourceforge doesn't seem searchable) Any help much appreciated, Dean Arnold ParAccel, Inc. ---------------------------------------------------------------------------- -- The Planet: dedicated and managed hosting, cloud storage, colocation Stay online with enterprise data centers and the best network in the business Choose flexible plans and management services without long-term contracts Personal 24x7 support from experience hosting pros just a phone call away. http://p.sf.net/sfu/theplanet-com _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users ------------------------------------------------------------------------------ The Planet: dedicated and managed hosting, cloud storage, colocation Stay online with enterprise data centers and the best network in the business Choose flexible plans and management services without long-term contracts Personal 24x7 support from experience hosting pros just a phone call away. http://p.sf.net/sfu/theplanet-com _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users
