Question

Which would be the proper way to install one publisher policy in to the GAC using WIX 3.5?
I tried to do this:
<File
Id="LIBGAC"
Assembly=".net"
KeyPath="yes"
Vital="yes"
Name="ClassLibrary1.dll"
ProcessorArchitecture="msil"
DiskId="1"
Source="..\ClassLibrary1\bin\Release\ClassLibrary1.dll" >
</File>
</Component>
<Component Id="Config" Guid="F089B1AA-B593-4662-9DF4-F47EB9FBA1F4" >
<File
Id="LIBGACPolicy"
Assembly=".net"
KeyPath="yes"
Vital="yes"
Name="Policy.1.0.ClassLibrary1.dll"
DiskId="1"
Source="..\ClassLibrary1\policy.1.0.ClassLibrary1.dll" >
</File>
<File
Id="LIBGACPolicyConfig"
Source="..\ClassLibrary1\policy.1.0.ClassLibrary1.config"
CompanionFile="LIBGACPolicy">
</File>
</Component>
</Directory>
When compiling with VS2008 appears this error:
policy.1.0.ClassLibrary1.dll appears to be invalid. Please ensure this is a valid assembly file and that the user has the appropriate access rights to this file. More information: HRESULT: 0x8013101b
And lastly, when compiling with VS2010 doesn´t appear to be any problem. But
at finalizing the installation process, the DLL is well installed and the
publisher policy didn´t. Also I read the log generated during the installation and I wasn´t able to find a cause.
Thanks for reading.

I've been doing something similar and works well using Visual Studio 2010 and in a Build Server with MsBuild:
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="ProgramFilesFolder">
<Directory Id="Gac" Name="Gac">
<!-- The component with the assembly -->
<Component Id="MiClassDLL" Guid="*">
<File Id="MiClass.dll" Assembly=".net" KeyPath="yes"
Source="$(var.MiClass.TargetPath)" />
</Component>
<!-- The component with the policy -->
<Component Id="PolicyMiClassDLL" Guid="{YOUR_GUID_HERE}">
<File Id="PolicyMiClass.dll" KeyPath="yes"
Source="$(var.MiClass.TargetDir)Policy.1.0.MiClass.dll" />
<File Id="PolicyMiClass.config" KeyPath="no"
Source="$(var.MiClass.ProjectDir)Policy.1.0.MiClass.config" />
</Component>
</Directory>
</Directory>
</Directory
In my case I have the policy.config file in the same project directory and I build the policy dll in the same output to make easier the installer script.
I noticed that the policy component must have a guid and for some reason it requires internally that policy dll and config files in the same directory/component.
I build the policy assembly in the Post-Build event of MiClass project with this command:
"C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\al.exe"
/link:"$(ProjectDir)Policy.1.0.MiClass.config"
/out:"$(TargetDir)Policy.1.0.MiClass.dll"
/keyfile:"$(SolutionDir)MyKeys.snk"
/comp:"My Company"
/prod:"My Product"
/productv:1.0
/version:1.0.0.0
I hope this works for you.

I did some work with policy dlls, and the only difference I can see is that your file naming convention is a little different than ours was.
Instead of
policy.1.0.ClassLibrary1.dll
policy.1.0.ClassLibrary1.config
We used
policy.1.0.ClassLibrary1.dll
ClassLibrary1.dll.config

instead of /link switch use /embed to compile the xml-config into publisher policy. then you can install the resulting assembly into GAC without problems
