Cannot load RevoScaler

I have just installed R evolution (Windows 7, 64 bit).

Immediately after loading, RStudio shows the following error:

Error : .onLoad failed in loadNamespace() for 'RevoScaleR', details: call: inDL(x, as.logical(local), as.logical(now), ...) error: The evaluation period has expired

I checked the following:

  1. .libPaths() gives the correct library path
  2. "RevoScaleR" %in% names(installed.packages()[1]) #TRUE

Any insight?

Solution

  • There last line seems to give some insight...

    The evaluation period has expired.

    Do you have a valid commercial license? If not, potentially there is your reason. If so, support should be your first stop.

    To ensure you have either a free developer version or a paid commercial version, here are some links:
