Adding Publisher & Security Cert to Macro Enabled Excel Application - Compiling with NSIS

[lnagel]

I have a an Excel Spreadsheet with Macros (and some XML also)that I have created an installer for using NSIS. Basically when user clicks application it installs the spreadsheet on the Desktop - Installs some documentation and installs a license file in the root of C:

Everything works fine except for Windows 10 (latest build) really dislikes unsigned applications

Can someone point me in the right direction - I need to added a cert (self signed?) and I need to add Publisher Information to the App

Thanks in advance
