i have the installation in hebrew but i dont know make cab filr for office.in addition the installation was needed serial
waht i need to do

By heart I would say that creating a silent installer for Office 2007 works the same way as for Office 2003, so I would advise you to read the Unattended Guide. In short, download the Resource Kit for Office 2007, create a transform file and create a silent, self-extracting archive of your installation files or an add-on for nLite; for that, see the nLite web site as you're bound to find more information on that there, or simply download any pre-built add-on, extract it's contents and study it to learn how it was built.

have you created this jet or can someone create this?

i want to add office 2007 to my windows installation too

ps i've got office enterprise 2007 dutch (with serial)

Use that to add your serial, edit the install options and create a MSP file (you need enterprise)

What to do with that?

if you can write a small step by step tutorial i will be very grateful

any settings you apply inside the .msp file will be automatically applied when someone clicks the setup.exe if you save it to the updates folder on the cd the /adminfile MSP_Name.MSP part is only needed if you have more than 1 admin .MSP file in the updates folder

so:
Step 1: copy the entire office source to network location, pen drive, or tempfolder to be burned to a cd/dvd
Step 2: execute setup.exe /admin (either use the command line or create a shortcut to setup and add the /admin part to the shortcut)
Step 3: fill out all the options in the admin GUI that you would like to use
Step 4: when you are done, you can save those settings to a .MSP file you can name it anything (ex: silentinstall.msp) and save it to the /Updates folder
Step 5: run setup.exe from whatever media you decide on and it will search the /updates folder, find your file and apply the settings you specified.
