I uninstalled Beta5 before upgrade to "LibreOffice 3.4.0RC1 – WIN7 Home Premium (64bit) [OOO340m1 (Build:11)]" (Custom - additional UI languages) without touching my user profile.
After Installation all of my frequently used dictionaries (German-Germany, English, French, Spanish) and also some seldom used (Hungarian, Danish) have been lost, only "German-Austria" and "Swaheli" still available
I remember Bug 37195 - no spelling after installing,
in particular: https://bugs.freedesktop.org/show_bug.cgi?id=37195#c4
'German (Austria)' and 'Swahili (Tanzania)', too. ;)
I could reproduce this bug several times
(with different versions of LibO 3.4 Beta, and last today with the 3.4 Dev Snapshots 2011-05-19 and 2011-05-20)
1. Uninstall/remove the older version of the program.
2. Install the new version and keep the same user profile.
My current workaround to get access to the bundled dictionary extensions:
1. Close LibO.
2. Go to your user profile: rename the folder 'bundled'
[path: '...\3\user\extensions\bundled'], e.g.: 'bundled_old'.
3. Restart LibO:
A new folder 'bundled' will be created in the user profile.
All bundled dictionaries will be available.
It seems that something with registering the bundled dictionary extensions is broken.

First start with the same user profile.

Renamed folder 'bundled' to 'bundled_old', and restarted LibO.
Indeed, knwon problem from "Bug 37195 - no spelling after installing"
thank you for finding the DUP
