Hi, today I tried to install SP1 office 2010. But i faced a strange problem that said "The expected version of the product was not found on your system." What I did so far : 1. Uninstall office 2010-->restart 2. Try this way to integrate SP1 into office 2010--> (I tried to link, but system refuse me to add the link)-->thread "Office 2010 Toolkit and EZ-Activator, page 356" 3. Install the office 2010 with the new installer-->but I still get a same number of office 2010 "14.0.4734.1000"-->its mean not SP1. 4. I tried again to install SP1, but the problem still persist. I have no idea how to fix this. Tried googling, but no much help. I use windows 7 ultimate 32 bit, Office 2010 32 bit. SP1 32 bit. [edit to add] the update of SP1 is not available in my windows update. My windows update is set to automatic update. Any help will be appreciated. Thanks.
