 # Troubleshooting
 
+## AutoHotKey executable not found
+
+If you try to start komorebi with AHK using `komorebic start --ahk`, and you have
+not installed AHK using `scoop`, you'll probably receive an error:
+
+```text
+Error: could not find autohotkey, please make sure it is installed before using the --ahk flag
+```
+
+Depending on how AHK is installed the executable on your system may have a
+different name. In order to account for this, you may set the `KOMOREBI_AHK_EXE`
+environment variable in your
+[PowerShell profile](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_profiles?view=powershell-7.4)
+to match the name of the executable as it is found on your system.
+
+After setting `KOMOREBI_AHK_EXE` make sure to either reload your PowerShell
+profile or open a new terminal tab.
