Hi Forum,
some days ago, I had the same problem and posted it as a support case.
I got a very fast answer by Tamila Ashrafova, and I hope I'm allowed to post it here:

I tried to investigate this problem and found that it is a bug in Visual Studio 2008 when it comes to building a 64-bit application on a 64-bit system. VS 2008 will use the 32-bit version of license compiler (LC.exe) when the build configuration is set to x64.
To workaround this issue you will need to modify your application project file in a text editor. Add the highlighted line shown below to all of your 64-bit build configurations:
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|x64' ">
<DebugSymbols>true</DebugSymbols>
<OutputPath>bin\x64\Debug\</OutputPath>
<DefineConstants>DEBUG;TRACE</DefineConstants>
<DebugType>full</DebugType>
<PlatformTarget>x64</PlatformTarget>
<CodeAnalysisUseTypeNameInSuppression>true</CodeAnalysisUseTypeNameInSuppression>
<CodeAnalysisModuleSuppressionsFile>GlobalSuppressions.cs</CodeAnalysisModuleSuppressionsFile>
<ErrorReport>prompt</ErrorReport>
<LCToolPath>C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\x64</LCToolPath>
</PropertyGroup>
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|x64' ">
<OutputPath>bin\x64\Release\</OutputPath>
<DefineConstants>TRACE</DefineConstants>
<Optimize>true</Optimize>
<DebugType>pdbonly</DebugType>
<PlatformTarget>x64</PlatformTarget>
<CodeAnalysisUseTypeNameInSuppression>true</CodeAnalysisUseTypeNameInSuppression>
<CodeAnalysisModuleSuppressionsFile>GlobalSuppressions.cs</CodeAnalysisModuleSuppressionsFile>
<ErrorReport>prompt</ErrorReport>
<LCToolPath>C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\x64</LCToolPath>
</PropertyGroup>

N.B.: Maybe you will have to replace the path to c:\Program Files by the appropriate naming for your local OS.
In Germany, it spells: c:\Programme ....
Adding these lines solved my problem, and I really highly appreciate that Aurigma is doing Microsoft's job...
Best regards
