Adobe Reader crashes on Win7

In the last few days Adobe Reader crashes upon opening a document, either through a browser such as Firefox or double-clicking on a saved PDF.

I tried repairing the app from the control panel, then uninstalling and installing the latest version. No change.

Here is the crash report:
