With the recent Windows 8 RTM I wanted to pull together a list of IRM related fixes. These are fixes for both the client and applications that utilize this functionality, primarily Office.
Here are some notes about this information.
Rights Management (RM) Client
RM Client Fixes
v1 SP2 client install required (MSDRM)
Included in OS (MSDRM)
Office 2013 adds the MSIPC client on Windows Vista, Windows 7, and Windows 8. There is no separate install needed and there are no fixes needed.
