Since installing Libre Office 4.4.4.2 I have had the following error

Hi

I am having the following problem starting any application within libre office. The following error appears in a dialog box entitled LibreOffice 4.4 -Fatal Error

The program cannot be started.
The service manager is not available.
("InvalidRegistryExemption:
file:///C:/Program%20Files%20(x86)/LibreOffice%204/program/services/servicesrdb: duplicate "
Start setup application to repair the installation from CD, or the folder containing the installation packages

I tried reinstalling 4.4.4.2 This did not help.
I have now tried installing 4.4.4.3 but this has not corrected the error

I am running windows 7 Home Premium Service pack 1 on a Samsung RF 711 with 8 G of ram i7-2670QM and 1.75 TB of drive space across 2 drives.

Any ideas on how to resolve this problem.

Thanks
