Hello my friend!
I was also thinking it was a language issue. It worked much better this time but we are not at destination yet!
The reset went through. I then installed (running in safe mode again as «Administrateur»; no network connection).
I think I saw a message saying that installation failed (for a very brief moment...). I was then asked to reboot.
I did the reboot and connected to my own account (with administrator privileges). IE7 is installed and works very well; Hotmail as well.
I tried then tried the two products in my wife's account (regular privileges). IE7 is there but suffers from the same problems. When it starts, it tries to execute this page
Customize Your Settings; an eror occurs. If I enter another address, it works. I f I try to connect to hotmail.com, execution of the login page fails the same way.
This is exactly the situation I had when I uninstalled IE7 in December!
New food for thought... I have attached the IE7 installation logs.
Thanks again!
