[wix-users] AllowDuplicateDirectoryIds build error

[robert_yang at agilent.com]

Hi, I just started converting one of our 3.10.3 projects to 3.11.0.1701 and am seeing the following error messages :

c:\WixVersions\Wix3.11.0.1701\wix2010.targets(2439,7): error MSB4064: The "AllowDuplicateDirectoryIds" parameter is not supported by the "Light" task. Verify the parameter exists on the task, and it is a settable public instance property.
c:\WixVersions\Wix3.11.0.1701\wix2010.targets(2435,5): error MSB4063: The "Light" task could not be initialized with its input parameters.

The .wixproj project file contains the following :

  <PropertyGroup>
    <WixToolPath>c:\WixVersions\Wix3.11.0.1701\</WixToolPath>
    <WixTargetsPath>$(WixToolPath)Wix.targets</WixTargetsPath>
    <WixTasksPath>$(WixToolPath)WixTasks.dll</WixTasksPath>
  </PropertyGroup>

This is so we can build Wix installers from an automated process (we've been doing this for a while), as per this help page :

http://wixtoolset.org/documentation/manual/v3/msbuild/daily_builds.html

Any idea what might be wrong or how to fix it ?

Thanks !
