First download sp1 (admin) and sp2 (admin).
There seems to be a little confusion as to whether sp2 is cumulative or not,
so the best way to go is first slipstream sp1 then sp2.
Instructions is as follows.
To make an admin install point, put ur office cd (clean, without sp1 slipstreamed) in ur cd drive & run the following command
x:\setup.exe /a (where x is ur cd drive)
Follow the instructions (install in c
ffice for convenience and ease concerning the following commands)
Extract sp1 to c
ffice
To update office, run the command.
msiexec /p c:\office\MAINSP1_Admin.msp /a c:\office\proplus.msi SHORTFILENAMES=TRUE /qb /L* c:\office\sp1Log.log
When its done run this command to update ur webcomponents.
msiexec /p c:\office\OWC10SP1_Admin.msp /a c:\office
\owc10.msi SHORTFILENAMES=TRUE /qb /L* c:\office\owc10.log
Extract sp2 to c
ffice
Run the command
msiexec /p c:\office\MAINSP2ff.msp /a c:\office\proplus.msi SHORTFILENAMES=TRUE /qb /L* c:\office\sp2Log.log
Again, to update office
To update ur webcomponents, run the command.
msiexec /p c:\office\MAINSP2ff.msp /a c:\office\proplus.msi SHORTFILENAMES=TRUE /qb /L* c:\office\sp2Log.log
To update an already installed version.
msiexec /i c:\office\proplus.msi REINSTALL=ALL REINSTALLMODE=vomus (office)
msiexec /i c:\office\owc10.msi REINSTALL=ALL REINSTALLMODE=vomus (webcomponents)
If no preinstallation just run setup exe.
Ur done.
If u like u can delete the service pack files, and of course burn ur slipstreamed admin install to cd. Just remember to keep ur "original" cd, for later slipstreaming etc.
Hope I haven’t missed anything.
Good luck
