These days I found my old Age of empires II Cd’s and i called my friends to play together as we did some years ago. I installed the latest version of Hamachi on Windows 8 (i use linux, but W8 was already installed and i kept it to play). I always got a message “Failed to connect to the engine” (german: “Die Verbindung mit der Engine konnte nicht hergestellt werden”). To solve the problem you can search for an old hamachi archive or do the following steps:
- Press WINDOWS + R, type in “services.msc”, search for “LogMeIn Hamachi […]”, right click, press start or restart.
- open notepad, copy paste the following code, save as “hamachifix.reg”, open it.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\LogMeIn Hamachi]
"EngineConfigDir"=""
hope it helps
