Applications Manager displays "Enter a proper Manageengine license file" during installation.
Reason1: If your system date is set to a future or a past date, you will get this error message.
Solution: Uninstall Applications Manager, set the system date settings to current date and time and re-install it.
Reason2: You might have applied the Professional Edition License in the Enterprise Edition Server.
Solution: You can check in <AppManager_Home>/conf/install.txt or AppManager_Home/conf/AMServer.properties file. Here check for am.server.type (AAM for Admin Server, MAS for Managed Server, NORM for Professional Server). If you have got License for Professional Edition, you need to choose Applications Manager as Professional Edition instead of Enterprise Edition while installing the product.
Also, make sure that the license file is not corrupted. If the problem persists, contact firstname.lastname@example.org with your license and contact information.
