Uninstall before installing an older version over a new one
For one reason or another, customers sometimes decide to install an older version of Macro Express or Macro Express Pro after trying a new version. As with any program, it is generally a good practice to uninstall before installing an older version on top of a newer version.

Many times installing an older version of top of a newer version does not cause problems but with some versions it will. If you have trouble after installing an older version on top of a newer version of Macro Express or Macro Express Pro, uninstall and reinstall.

After installing Macro Express Pro v 4.1.0.1 you will need to uninstall if you decide to install an earlier version.

A complete list of changes:

Enhancements

1. Removed the 'Debug Variables' pane from the script editor. The variable values are now contained in a new, floating window. This window is available under Debug > Show Variable Values. Also, the window will only show the variables that have been modified, making it easy to see what variables are in use by the macro.
2. Added an option to convert a date/time variable to a string in the 'Variable Modify Date/Time' command.
