You can't link the WIn 7 activation to the MSA. Can you go to start and type "winver" (without the " ") and press OK? and then it will show the build.
version 1909 (os build 18363.418 ive just looked on my key details and it says type OEM.SLP google says i might have problems, lol thanks for taking your time to assist me so far Enthousiast
oem:slp is not an activation key without the SLIC and Certificate and only works on Vista/7/some servers. I've sent you a pm.
