How to Update License of RAC 2010 Like in Autocad

[bingles7]

Autocad is good.

I've never used Autocad ;) but in Revit,
click the Help dropdown - top right corner in 2010 - the little triangle just beyond the question mark button and choose 'About'.

There is a button in the pop-up 'Product Information' which if you click it will produce another pop-up where you can update your serial number.

Hope that helps.
