Is it possible to purchase individual items for personal use like Photoshop and Acrobat Pro for example?
You may buy Photoshop Elements with a serial number, not a subscription
Buying version 15 is 64bit only http://www.adobe.com/in/products/photoshop-premiere-elements.html
Buying Elements online is for ONE platform https://forums.adobe.com/thread/2245264
-be VERY SURE you select the Mac or Windows version that you need for your computer
