Getting this error on ALL ClickOnce application launches for a certain user. This started happening after a version upgrade (but happens to no one else).

My problem was caused by a change in the csproj file. a reference to an assembly was changed from:
HintPath>..\Files\
to
HintPath> .. \ ..\Files\
which added a dependency xml element in the manifest file.
editing the csproj file and publishing, fixed the manifest file.
