Prepare LibreOffice MSI to deploy with GPO
The problem is that LibreOffice supports multiple languages when installing. So in order to deploy the MSI through GPO you need to set only one language:
- Download MSI package from www.libreoffice.org
- Download and install InstEd
- Open InstEd and then open the libreoffice msi
- Select Tables -> Summary Info
- Change the language field to 1033 (1033 is for english, adjust for other languages)
- Save the file and install it through GPO
