You do not have to uninstall any previous IE version to be able to install IE7 Beta 2. This is actually an UPGRADE.
Second thing... you can not install IE7 Beta 2 before you pass the validation process. If you are running pirated version of Windows OS, you won't be able to install it.
Im kind of stupid , but where can i go to see this?
Logg files are always in the same place... right click
MY COMPUTER icon, choose
MANAGE. When new window is open, press on the little plus (
+) sign next to
Event Viewer in the left panel. Choose the section you are interested in, click on it and take a look in the right panel for results.
