Thanks for your replies!
I'm not Chinese (Dutch) and I don't need and want a Chinese language pack. I have never (knowingly) installed such a language pack so instead of (re)installing one, I'll rather uninstall this one...
But given the corrupt nature of the installed one, maybe I would need to correct the situation first by (re)installing the language pack?
I'm running the W7 Ultimate version.
I've found something related in the CBS log, I'll attach that part.
Do you still advise me to reinstall the Chinese language pack?
Thanks!
Michel
