This is an installer for the new implementation of the ingame tech tree view (F2). For the main project see https://github.com/Janworks/AoETechTree.
Unpack the EXE and DLL files into an arbitrary folder and run the EXE file. It will ask you for the age2_x1.exe, after that click "Install". This will patch your EXE and copy the TechTree.dll into the age2_x1 folder. If you haven't already created a custom empires2_x1_p1.dat with the new tech tree, you can unpack the empires2_x1_p1.dat from the archive into your DATA folder, replacing the old one (do not forget a backup!). Now you can start your age2_x1.exe as usual. It will automatically load the new tech tree and display it ingame.
