Yes. You can install the application in any sub-folder.
Most of the user ask this question that can laravel application be installed on any sub folder. Answer is yes. You can install it any sub folder. Copy downloaded zip file in your folder & extract all the contents of zip file into the same folder. Lets take example of both live & localhost server:
Application installation on sub-folder (Live Server)
You can create subdomain & point it to the folder(where you want to install the application) to access Script Mint applications. Now you can access your application at /install path.
Application installation on sub-folder (Local Server)
You can create virtual host & point it to public folder of the application. Below are some tutorials to create virtual host on local server.
|Windows or Mac||MAMP|
If you still think, you are not able to install this application in sub folder, just try to install a fresh Laravel application in sub folder with your own method. If you are successful to run that Laravel installation then you should be able to access the application also.
Make sure you point virtual host to public (public folder of the application) folder. Now you can access your application at /install path. Don't forget to set config folder & storage folder and its files writable.
