How to correct registry errors?

I use Knoppix Image 7.2.0 with LibreOffice version 4.0.3.3(Build Id. 400m0(Build:3))

Of late, I get this registry error when I click to open LibreOffice.

When I read and click Okay, it closes.

The problem is that everything came with the knoppix ISO image and there is no additional Installation CD.

The program cannot be started. The service manager is not available. ("spurious end tag in file:///home/knoppix/.config/libreoffice/4/user/uno_packages/cache/registry/com.sun.star.comp.deployment.component.PackageRegistryBackend/common_.rdb") Start setup application to repair the installation from CD, or the folder containing the installation packages.

I have tried with renaming the common_.rdb file. I also tried copying the said file from my desktop to my laptop, but then the application doesn’t start at all.

What else to do?

Klaus2008 in the Knoppix Forum solved this problem. he advised:

`I woud suggest you look at Cannot start LibreOffice 4.0 due to Fatal Error Message and then follow the instructions at Resolving corruption

The directory you should rename is /home/knoppix/.config/libreoffice/4/user`

Followed the instructions and the problem was solved. Old settings are gone. Nonetheless the I can use Libreoffice.
