How to Install FarCry 1 with Windows 10

Every Action should be performed with Admin Rights!

1. Install FarCry1 to C:\ not to C:\Program Files (x86)\Ubisoft\Farcry... Important!
2. Install the "farcry_amd64upgrade_xx.exe" (xx depends of the language) Update.
3. Install the "farcry_amd64_ecu.exe" Update.
4. Start Farcry (64bit) with Admin Rights. No compatibility mode is needed.

That's all! Everything works fine (Tested with Windows 10 Professional (64bit))
