Sometimes a launcher app icon isn't created for programs installed in Crossover. You can use this process to manually create launcher app icons.
This process is also useful 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.
Please note the launcher app icon that's created is tied to where the .exe is located when the app icon is created. If you move the .exe the launcher app icon will stop working and need to be recreated.
