CR9 Viewer Automation Error with IE7

I have a user that has an application implemented with VB6, Access, and Crystal Reports 9. The app uses the Crystal Reports Viewer Control on the report forms. The app worked fine with XP and IE6. The user is an AOL user, and AOL helpfully installed IE7 and the app stopped being able to produce reports. Now, when a report is run two errors occur: 1) Automation Error the callee (server [not server application]) is not available and dissappeared: all connections are invalid. The call may have executed -2147418105 and 2) Runtime error 50003 Load Report Failed.

I did not know that crystal reports had any dependencies on the browser, but I see from web searches that other CR users have had issues with IE7. They listed adjustments to the security settings in IE7, which I tried but which had no effect for me. I set it to basically have no security at all and it still made no difference for me. Does anyone have a clue what my problem is? (be nice...)
