If you just run windows update it will find all needed updates. Install all windows updates especially anything related to .NET.
I think the problem on your system is it is not up to date so it doesn't recognize updated culture names as described in this blog post:

If your system is not up to date it will not recognize the culture zh-hant and this will cause the error you are seeing.
So there are 2 possible ways to fix it, the best way is to update your system so it recognizes the new culture names.
If that fails you can delete the file Web/App_GlobalResources/Resource.zh-hant.resx or rename it to Resource.zh-CHT.resx (which is the old name)
Hope it helps,
