Sometimes a launcher app icon isn't created automatically for programs installed in Crossover. You can use this process to manually create double-clickable launcher app icons. You can also use this to create a double-clickable app icon for standalone .exe programs that have no installer.
First go to the Bottle menu and choose Run Command...
Next choose the bottle that contains the Windows .exe. If this is a standalone .exe don't worry about the bottle.
Browse and select the Windows .exe.
Back on the Run Command window click Save Command as a Launcher.
A Finder window may popup with the new launcher app icon. You can also double-click the new launcher icon in Crossover.
Note: The launcher app icon is tied to where the original Windows .exe is located. If you move the .exe the launcher app icon will stop working and need to be recreated.
