to the new complete installation file my windows 7 was saying :
<< another version of this product is already installed. The installation of this version can not be continued. Use Control Panel "Programs and Features" to configure or to remove the installed version of this product.>>
I was asking whether I should deinstall the previous version , but when I start my work you are starting to sleep (Europe !!!)
Finally, I have let my windows 7 repair the previous install, I guess it updated / corrected this famous database and I could install the update, works fine ...
Thanks a lot all over there:
