As you know, the default size upload limit for a SharePoint web application is set to 50 Mb.

Usually, you change this settings to allow higher upload size.

On my SharePoint environment, I usually set this with a very high value, such as 5 Gb.

So I wanted to do the same on my fresh SharePoint 2010 RTM installation, and I have an error message which says: The value for maximum upload size is invalid or out of range. The maximum value is 2046 MB.
