Working on Windows 8.1. Had upgraded LibreOffice from 4.4.5 to v5. Subsequently upgraded to v5.0.1 bug fix release. Didn't notice any problem when using this. Then upgraded to v5.0.2. LibreOffice did not work after this, it crashed when opening some documents. Note sure why. Uninstalled and re-installed LibreOffice and the document crashing went away. Noticed the other evening that in writer spell checking as you type was not working. When I tried manually spell checking the document the spelling checking box opened, but then the window that says it has finished appeared almost immediately saying "The spellcheck is complete." Obvious spelling mistakes were not being flagged. I did an internet search and found references to people have had the problem before about the spell checker not working and that I should check if: Tools -> Options -> Language settings -> Writing Aids and if the "Writing Aids" "Available language modules:" box was empty, as that was the problem. It was empty. Note that in the "User-defined dictionaries" box below, en-GB, en-US, standard and technical dictionaries are defined and enabled. In the "Options:" box "Check spelling as you type" etc is also enabled. The suggested fix was to download and install the "English Dictionaries" (dict-en.oxt) extension. I downloaded this, but when I tried to install this using: Tools -> Extension Manager… The first time I tried to open the extension manager nothing happened, trying a second time and the extension manager opened. As soon as I pressed the "Add…" button a pop-up window with a fatal error message appeared (the message is below). On pressing "OK" in the pop-up window LibreOffice closed. Window banner message: LibreOffice 5.0 - Fatal Error Window body message: [context="user"] caught unexpected com.sun.star.deployment.DeploymentException: Extension Manager: failed to read data entry in configuration backend db: file:///C:/Users/Colin/AppData/Roaming/LibreOffice/4/user/uno_packa ges/cache/registry/com.sun.start.comp.deployment.configuration.Pack ageRegistryBackend/backenddb.xml I noticed that this message was referring to "LibreOffice/4/" and I am using LibreOffice 5. I have tried uninstalling both the language pack and LibreOffice, re-booting the PC and then installing again, re-booting the machine. Both problems (no spell checking and extension manager fatal crash) still occur.
(In reply to junk_2010 from comment #0) > I noticed that this message was referring to "LibreOffice/4/" and I am using > LibreOffice 5. The folder name wasn't renamed to 5 so the user profile would not reset. This was a decision by the engineering steering committee.
Uninstalled 5.0.2.2 and GB language pack Installed 4.4.5.2 and GB language pack. On starting LibreOffice had the basically the same fatal error as with version 5: Window banner message: LibreOffice 4.4 - Fatal Error Window body message: [context="user"] caught unexpected com.sun.star.deployment.DeploymentException: Extension Manager: failed to read data entry in configuration backend db: file:///C:/Users/Colin/AppData/Roaming/LibreOffice/4/user/uno_packa ges/cache/registry/com.sun.start.comp.deployment.configuration.Pack ageRegistryBackend/backenddb.xml which is the same error as before except that the Windows banner title has "4.4"in rather than "5.0"
Uninstalled 4.4.5.2 + GB language pack Deleted user AppData/Roaming/LibreOffice folder tree. Installed 5.0.2.2 + GB language pack Everything now working correctly. Tools -> Options -> Language settings -> Writing Aids The "Writing Aids" "Available language modules:" box was no longer blank, it had 4 entries. Tools -> Extension Manager… This opened first time and listed five entries for items like: Spelling, Solver for Nonlinear Programming and Wiki Publisher. Spell checking was now working in writer. So I presume that whatever was "corrupted" somewhere in: AppData/Roaming/LibreOffice/… was causing the problem.
