Are there two seperate packages you have to install, one for Windows Store 8.1 and one for Windows Phone 8.1?
Yes, in fact the SQLCipher for Windows Phone comes in two separate packages, one for 8.0 and another for 8.1. SQLCipher for Windows Runtime is a separate package as well.
Thank you Nick for your prompt reply. Does this mean I need to buy separate licenses as well?
Windows 8.1 and Windows Phone 8.1
