When installing the 3.52 version as an update, the installation (of the suite) correctly recognised the previous installation - "G:\Program Files (x86)\LibreOffice 3.5" However, when installing the Help file it did not, and incorrectly offered "C:\Program Files (x86)\LibreOffice 3.5" as the path. Neither installation recognises the registered (or previous installation user name and incorrectly offers Installer as the name. It should pick up the user login name, or the name used in the existing installation. This has been a 'feature' with previous versions of LO.
