I have the PT version of Microsoft Office 2007, and I have installed it on my Lubuntu with PlayOnLinux with sucess. However, I can't install any service pack. First I've tried the service pack 3, and nothing. Then service pack 2, and finally the service pack 1. None of them work. I get this error (since my version of Lubuntu is in Portuguese, I will try to translate it to English): office2007sp1-kb936982-fullfile-pt-pt.exe has encountered a problem and needs to close. We are sorry for the inconvenience. This can be caused by a problem in the program or a deficiency in Wine.
