Problem: Every time I open Internet Explorer, an installation wizard for erwin comes up.
Solution: This happens when a Java-IE Add-On is installed in a Windows SP upgrade, but it is not needed to run erwin, so it can be removed.
To remove add-ons from your PC
From the Tools menu option select Manage Add-ons
Scroll down to Sun Microsystems, Inc
Locate the plug-in named JQSIEStartDetectorImpl Class and click on disable/remove
