A common question that pops up quite often is the support for SoftGrid on non-English platforms. Whether this be the Management Console or other Core component.
We plan to address this in later versions of SoftGrid in the Future but currently this is not the case in 4.1 or 4.2.
KB http://support.microsoft.com/kb/935684/en-us explains this in more detail.
We require the server infrastructure to be in English to avoid potential problems.
Bring on 4.5 to sort this out!! 🙂
