In order to use JPA Designer you must enter valid user registration details and the program must be able to check the status of your licence against our licensing database.
When you first install JPA Designer the program runs in demonstration mode and will not display the results of calculations, nor allow EPCs to be lodged. In order to access the full functionality of the software you must enter the user name and keycode(s) you received when you bought a licence for one or more program modules.
To enter licence key codes:
At	the Project	Manager window	click on the key code icon (gold key button). The User	Registration dialogue	opens. 
If	you	have	licensed	two	modules	make sure you	put	the key	codes	against	the	correct	modules. The	company	name	is	case	sensitive	and	should	be	written	exactly	as	shown: so if, for	example,you	enter Limited, when	the	company	name	with	the	key	code contained Ltd the	program	will	not	accept	the	key	code. In	the	key	code, 1	=	one	and	0	=	zero.
Because licences for JPA Designer SAP and Uvalue modules generally run for a year* the program has to check whether your licence is still valid. It does this by contacting our on-line licensing database and checking the expiry date for module.
The program will try to check the database the first time you open a SAP or U-value calculation after the program itself has been launched.
If you often use JPA Designer away from the office there are two features you can use to prevent problems with the licence check:
The Project Manager tool bar	displays the length	of	time since	the	last successful licence	check: provided	the	values	shown are green the module will open.
* The PV and Wind Turbine module does not have an annual licence, so will not expire. It will, however, still require internet access to check the licence is valid.
