Hi. I am new there. Please let me know how to download from Assets Store. What I need to do for being able to free/paid download ?
Hi,
a) Download and install the latest version of Unity
b) After the registration go to the menu Windows + Asset Store
c) You must need an valid count for downloading free Asset and a Paypal count for buying the others.
That all.
Welcome on board. 
Thank you for swift reply
The free version of Unity is only 30 days. Please let me know if I will can use Assets Store after this period of time.
the trial version is for unity pro features. after this period you’ll end up using the free version only. So nothing to worry about.
