Ok so i recently updated Libreoffice from 4.3 to 4.4 and recently 5 it worked for to days but i cannot get it open now message reads (premature end of file:///C:/User/Chris/AppData/Roaming/LibreOffice/4/user/extensions/ bundled/registry/com.sun.star.comp.deployment.component/Package RegistryBackend/common_.rdb

Now i have looked at answers ie removing the extension but the message still comes up.

i use a hp laptop with windows 8. can anyone help

Try the Profile reset, as shown in Q56017. If that gets your system working again, then you will need to reinstall any customisations such as Extensions.

If this helps then please tick the answer (:heavy_check_mark:)
