Purchasing License for HEW Tools / v6.00 R00

Hi, we have a product using the M16C MCU that we've managed to upgrade to the v6.00 R00 compiler toolchain - currently using the evaluation version.
What is the best way to purchase a license for this version of the toolchain.
We've found that Mouser have the following:
au.mouser.com/.../YRTA-HEWNC-1U
and on digikey:
www.digikey.com/.../en

What version would be received if purchasing YRTA-HEWNC-1U from either of the above suppliers?
