I'm very new to KNIME and have been trying to read my SAS files using the Read SAS7BDAT (DSREAD) node. I've added a path and tried to run but get the following error:
I believe that SAS reader only works with 32-bit operating systems. Interestingly, GGASoftware just released a GPL SAS7DBAT library for Java, so I guess that someone will write a node for KNIME using this before too long. It looks like low hanging fruit to me.

Until that happens, the foreign package in R is probably your best bet.
