The bar graph advnced suddenly quickly after my initial posting, but still it took over one hour. Installation was done from the DVD and selectively for Word, Excell and Office Tools. During the installation the machine was left untouched. I tried those installed and found nothing wrong with them.
The power line was interrupted in the middle of the installation process and I had to start over from the beginning. I do not know if this is something to do with abnormally long time to install.
