Panda 2 upgrade

Hi,
I have a Panda 2 board which I haven’t used for a while. I want to use it for a new project but I’m now using VS2015 and the net framework is version 4.3. The board is v 4.1.5.1.
Can I upgrade?
If so where will I find the file to use?
Many thanks

You cannot upgrade the Panda 2 past 4.1. You can, however, install 4.1 in VS2015. 4.1 is no longer installed by default, but can be downloaded here. It may even be included in the installer under advanced options.
