Wix Duplicate Symbol Error

Question

I am new to wix and I am having to add a dll to two separate folders as it is being used by two separate part in my application, but I am getting a duplicate symbol found error, how can I go about resolving this issue?

Answer 1

First, create multiple component groups that target different installation locations. They contain the same DLLs/files. Then, give also a unique identifier for those DLLs inside the respective components with Id attribute.

For example:

<ComponentGroup Directory="FirstDirectory">
    <Component Id="Component1">
        <File Source="MyFile.dll" Id="MyFile.dll.InFirstDirectory" />
    </Component>
</ComponentGroup>
...
<ComponentGroup Directory="SomeElseDirectory">
    <Component Id="Component2">
        <File Source="MyFile.dll" Id="MyFile.dll.InSecondDirectory" />
    </Component>
</ComponentGroup>
