Greetings, I just got bitten by this problem after updating to latest weekly release of WiX.
Turned out to be the wixproj file not having the default Platform property specified, which is easily fixed by adding: <PropertyGroup> ... <Platform Condition=" '$(Platform)' == '' ">x86</Platform> ... So it looks like MSBuild defaults to AnyCPU even though I didn't (and can't!) have AnyCPU defined as a platform for any configuration options in the wixproj. Not sure what can be done about it, but figured it was worth a mention so others don't waste time on it. If it matters, this solution & project was converted from VS 2005 -> 2008 a while ago and solution is now at Version 10.00 and project at ProductVersion 3.0 and SchemaVersion 2.0 when the problem struck, so it may be a fairly esoteric issue. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users
