Milo,
The fact remains, only VLK/FPP licenses are transferrable. Discounted licenses (MLK,OEM, PKC etc.) are not.
From
this Microsoft page :
How many licenses /installations do Office Product Key Cards allow?
Each Product Key Card allows one user to activate one Office 2010 suite on one preloaded PC.
Can I install an Office Product Key Card on more than one PC?
No. The Office Product Key Card can only be installed on one PC. If you ever need to reinstall Office you can do so on the same PC on which Office was originally installed.
