The bundled extensions Presenter Console and PDF Import are deactivated in pre-tag versions of LibO 3.5 beta 1 ( f923851-7f15fca-1f1fd1a-ca8e46d-5bcbce4 ).
In the extension manager, for both extensions, a "/!\" is shown, along with the text "Error: The status of this extension is unknown."
(Windows 7, 32-bit, Oracle Java 1.6 U29 is installed)
I can confirm that the same happens under Win XP Pro x86 SP3
These extensions don't work under version 3.5.x
This is a regression from 3.4.4
I can confirm this on Windows 7 x86-64 to. JRE: Oracle 1.7 64Bit
