I created a Playable Macro but the .mxe file will not run.

Here are a couple of ideas. One is that you are trying to run the .mxe file on a computer without Macro Express installed on it. Macro Express must be installed on the computer where you plan to run the Playable Macro.

The other problem could be that Windows doesn’t recognize that the .mxe file is supposed to run with Macro Express. Reinstall Macro Express to fix this.
