I got a mail and install .jar file also but when I double click it on on .jar file its not launch browser page is not open. crx-quickstart in that only logs folder is available.
i have a license key and i have also install jdk 1.8 in my machine.
Can you review the error log for any specific msgs?
You have to specify the run modes while starting an AEM instance. There should be multiple folders created within the crx-quickstart folder so the installation is not complete/done correctly thus you won't see the welcome screen on the browser.
