Hi Manuel

I second your concern. Extensions are a potentially security hole and it 
should be possible to install LibreOffice without the ability to install 
extensions. The extension installer, expecially the GUI should be an 
option at intall time.

It has been noted here:


If you want no extensions at all (can break something, I have not 
tested), you must erase unopkg executables from your installation.

But if you want only to disable the GUI, de-register the proper dll in 
the command prompt:

C:\Program Files\LibreOffice.org 3\Basis\program>..\..\URE\bin\regcomp 
-revoke -r services.rdb -c 
revoke component 
dll' from registry 'services.rdb' succesful!

swoosh!, vanished.
