The version I'm talking about is the original App Launcher from Google that resides on your desktop Taskbar not in the Chrome browser:
Back to the issue:
If at some point you get an error that stops your Chrome App Launcher from launching and instead launches a standard window you should just need to correct the link so that the App Launcher works again. This can be done by completing the following steps:
- Locate the shortcut that's not working, whether it's on your desktop, Quick Launch Toolbar or Start Menu.
- Right click the shortcut and go to "Properties"
- In the "Target" box go to the very end of the path and type " --show-app-list" i.e. it should look something like this: "C:\Users\username\AppData\Local\Google\Chrome\Application\chrome.exe --show-app-list"
