This is a fix for the missing MAPI marshalling registry keys for the click-to-run (C2R) Outlook 2013 instalations.
Apply the relevant registry file if you are experiencing "interface not supported" errors from Redemption.

If you are using a 32 bit version of Outlook 2013 on a 64 bit OS use
Outlook2013_C2R_32_on_64.reg 

In all other cases (32 bit Outlook 2013 on a 32 bit OS or 64 bit Outlook on a 64 bit OS) use
Outlook2013_C2R.reg 

The files are identical except for the "Wow6432Node" part.
