The SysRestore plug-in for NSIS packaging system forked and used by Npcap. This plug-in is used to create a system restore point during Npcap installation.

Visual Studio 2013 (it's static linked, so no need to distribute additional DLLs)

1. Copy the built ANSI x86 version SysRestore.dll to your C:\Program Files (x86)\NSIS\Plugins path (most people use ANSI by default).
2. Feel free to use SysRestore::XXX functions in your .nsi script.
