Internet Explorer 7/8 Notice

To run models with Internet Explorer 7/8, use the following steps: (1) When you click on a Model Link and see the dialog "Do you want to open or save this file?", choose "Save" and pick a location on your hard disk. (2) When you see the dialog box "Download Complete," choose "Open." You can run models directly without saving a copy on your hard disk using other browsers such as Firefox or Internet Explorer 6.

Good news. Internet Explorer 9 works just fine with EconModel.  You can run models directly off the website without the "save" step.
