Dependent builds for .NET duplicate and code inspections

I tried setting up a build configuration with a dependency on another build configuration that builds on SNV check in.  The inspection build runs at night since it takes so long( Running on old computer).  I thought I could set a dependency so it would not have to build again if the last build was successful.  Apparently I'm not doing something correct since the build errors with:

 Step 1/2: Copy of Find Duplicates (Duplicates finder (.NET)) (37s)

[00:05:55] [Step 1/2] JetBrains Duplicates Finder for .NET



[00:05:55] [Step 1/2] Running in 32-bit mode, .NET runtime 2.0.50727.3082 under Microsoft Windows NT 5.1.2600 Service Pack 3

[00:06:30] [Step 1/2] Step Copy of Find Duplicates (Duplicates finder (.NET)) failed

At the top of the build log when copying that I did see:  Clearing temporary directory: C:\TeamCity\DotNetBuildAgent\temp\buildTmp  
Is that the issue?  I've scoured the TeamCity docs, but find most of Jetbrains documentation unhelpful.  I need examples.
