Here is a summary: "There is an updated SData Installer available for Sage 100 that works with Server 2012 R2. See the Support KB (75460) on the knowledgebase. I have verified this install works with Server 2012 R2. Note: This installer can be used will all versions of Sage 100 that support SData. For now, please use the updated SData installer available from the KB entry/tip to install the SData Native Provider Adapter on Server 2012 R2."
