Are you getting "blank page" or "License File could not be found error"?
If yes then only you need to run the following command,
"path/to/Ampps/php/php.exe" -c "path/to/Ampps/apache/php.ini" "path/to/Ampps/ampps/softaculous/enduser/install.php"
If you cannot find the install.php file in path/to/Ampps/ampps/softaculous/enduser/, then run the following command,
"path/to/Ampps/php/php.exe" -c "path/to/Ampps/apache/php.ini" "path/to/Ampps/ampps/softaculous/cron.php"
If you are not getting any of the above errors mentioned then there is no need of running these commands, they have been already executed successfully and your AMPPS is working fine.
