We are trying to use the Deployment Framework for BizTalk (BTDF) which uses BizTalkDeploymentFramework.WiXSetup.targets, when we use the target name of "installer" the deployment from BizTalk actually does a *.* delete on all of the file from the root C:\ directory.

It hoses a machine as it has a UAC prompt we have to accept.

Here's the log file from the Wix Target's the are executing.

Why would using the "installer" start deleting files.

The delete is based on the MSBuild property OutputPath, which is evidently not being set in your case.  The OutputPath property is part of the default Debug and Release PropertyGroup's in the .btdfproj.  A piece of the default is shown below:

  <PropertyGroup Condition="'$(Configuration)' == 'Debug'">
    <DeploymentFrameworkTargetsPath>$(MSBuildExtensionsPath)\DeploymentFrameworkForBizTalk\5.0\</DeploymentFrameworkTargetsPath>
    <OutputPath>bin\Debug\</OutputPath>
    <!-- Get our PDBs into the GAC so we get file/line number information in stack traces. -->
    <DeployPDBsToGac>false</DeployPDBsToGac>
  </PropertyGroup>

You should be passing in either a Debug or Release configuration and calling the Installer target.
