When trying to start Libre Office 4.1.5.3. I get the following error message "System cannot find file specified" how do I solve this problem?

Libre Office version 4.1.5.3

I would try to re-install or repair the installation. Depending on the OS this could be different.

To be on the save side, I would download from http://www.libreoffice.org/

Thanks for your help, I have installed Version 4.2.1, this is now working ok

I am glad I could help. If you think it is appropriate please check my answer as correct to get you question out of the list of unanswered questions. Thank you.
