It's been a long long time since I last installed office, so go easy on me chaps... I've had a request to install office 13 on a win7 laptop, I already have :SW_DVD5_Office_Professional_Plus_2013w_SP1_W32_English_MLF_X19-35821 and this is unpacked and ready on a thumb drive. Also have the latest 2.5.3 of MS toolkit ready. I had a look at the install instructions for 2010 from http://forums.mydigitallife.net/threads/21062-New-Office-2010-Repository and i noticed that i can install using one of the keys included in the post, ...... but I just needed to know if I still need to use the same keys to install the version of 2013 I am going to use, and would i need to use "ms toolkit" and the "channel changer". Or is X19-35821 already a volume edition?? and not need the "channel changer". I had a look at the new repo here http://forums.mydigitallife.net/threads/58332-The-Office-Repository and it just states :You can install Office 2013 using a Retail or Volume Key (MAK or KMS). Sorry if this seems a little stupid but as I said, it's been a long long time.... sorry chaps. P.S. win7 is 64 bit but i prefer to use the 32bit v of office. Thanks chaps for advice and any help given,.... as always, it is very much appreciated.
