%s

Parameters

%s
Full path to the file in question.

Background

Windows side-by-side manifests use XML-based .manifest files to describe their identity, optional dependencies, and optional member files.

In the present case, you were trying to add an assembly using a file that does not look like a side-by-side manifest file. This indicates one or more of the following problems:

Note that XML tag names are case-sensitive; an <Assembly> tag is not the same as an <assembly> tag.

Solution

Select a valid Windows side-by-side manifest file. If the file in question is supposed to be the manifest file, then you may have to correct its XML syntax. Consult the Microsoft documentation for the required side-by-side manifest syntax.
