Some people are experiencing issues with LibreOffice Portable 3.5.0. This topic is to discuss and nail down the bugs behind a couple of those issues. Some background details on some of the issues are in this thread.
1. Path too long. On some PCs with some installs, too long a path can lead to issues. This is NOT something we are addressing in this thread, regardless of your opinion of whether it should or should not be an issue or should or should not be warned about by the installer or platform. If you have LibreOffice Portable installed to a long path, please do not participate in this thread. We're worrying about other bugs and anything related to oddball paths working or not is a distraction.
Fix: Just install to a shorter path. X:\PortableApps\LibreOfficePortable is the recommended path.
2. McAfee being dumb. McAfee went off and decided that a couple random files in LibreOffice Portable were infected and deleted them without asking whether you wanted to. This is a false positive on the part of McAfee and you will be unable to use LibreOffice Portable (and possibly LibreOffice as well) until they fix their broken definitions. If you are experiencing this issue, please do not participate in this thread. We can't do anything on our end to fix McAfee's bugs.
3. Upgrade issues. Upgrading some working installs of LibreOffice Portable 3.4.5 to 3.5.0 causes it to stop working. However a clean install on the same machine works fine. This is one of the issues we are discussing but you have to be sure that a clean install is working and the upgrade is not to ensure this is your issue. This issue seems to manifest as LibreOffice freezing part way through starting up.
4. Outright failure. On some PCs, LibreOffice Portable 3.5.0 fails to work at all. Even thought it is a clean install into a supported path like X:\PortableApps\LibreOfficePortable. A quantified version of #4 is the error "Fatal Error - The application cannot be started. an error occurred during file opening". We can reproduce this reliably on a clean, fully patched Windows XP SP3 test machine and are working on a fix. Note that installing LibreOffice locally allows it to work. Uninstall and it starts failing again. So it is something else being registered by LibreOffice 3.5's new MSI installer.
Temporary Fix: As a temporary workaround, install the current Microsoft Visual C++ 2008 Runtime on the local machine to alleviate the issue. A permanent solution within the portable package itself is being worked on.
