+    The indexing filter library ooofilt.dll is linked against a couple
+    of libaries (e.g. stlport, uwinapi, ...) which are not standard on
+    a windows system. Unfortunately the library will be loaded by the
+    indexing service via LoadLibrary so that the libraries ooofilt.dll
+    depends on need to be in one of the standard search directories or
+    the <office installation> directory need to be added to the PATH
+    environment variable. In order to prevent failures while loading
+    the ooofilt.dll we're installing and registering this proxy library
+    which will load ooofilt.dll using LoadLibraryEx with the flag
+    LOAD_WITH_ALTERED_SEARCH_PATH (see MSDN for details). This approach
+    ensures that all libraries ooofilt.dll depends on will be found.
