Recently, I heard from a customer who has a system with Update Rollup 2 for Windows XP Media Center Edition 2005 and a localization pack that is used to add support for one of the new locales that was added in the Update Rollup 2 product. However, the customer ran into a problem that caused them to need to re-install their OS. After re-installing the OS, they were unable to re-install the localization pack and their Windows and Windows Media Center UI displayed in English instead of the language of the localization pack. Attempting to re-run the localization pack setup displayed an error stating "Installation of more than one Localization Pack for Update Rollup 2 for Windows Media Center 2005 is not supported."
If you run into a similar scenario and need to be able to re-install a localization pack for Update Rollup 2 for Windows XP Media Center 2005, you can use steps like the following:
- Click on the Start menu, choose Run, type cmd and click OK
- Run this command: reg delete "HKLM\Software\Microsoft\Windows\CurrentVersion\Media Center\Language Pack" /f
- Use steps like the ones in this blog post to locate and uninstall the MSI for the localization pack that was previously installed on the system
You should be able to re-run setup for the localization pack after completing the above steps to clean off the previous installation of the localization pack.
