Q: The REGISTER.EXE keeps failing to register or Patch says i need to register my gameA1: It's not a problem if it says you need to register your game ( again ).A2: Since the registration process uses Internet Explorer to acces the Internet ( no matter what your default web browser you have ) you'll need to have cookies enabled in it, it helps to clear the cookies before attempting to register. Also, since the cookies need to authenticate with a server, it's recommended to have an exact timezone selected and an updated time for your system, or else the cookies can expire as soon as they're created, intrerupting the communication process.A3: If on Vista run the Patch and/or REGISTER.EXE as AdministratorA4: If you encounter an HTTP error "12057" you'll need to uncheck the following option in Internet Explorer: Tools -> Internet Options -> Advanced -> Security options -> "Check for server certificate revocation"A5: You basically need to STOP any firewall/antivirus that can interfere with the online key checking, have all updates for Windows and IEA6: Try to write the key/password with small case letters, even by changing your password with one that has small case letters A7: Try to run REGISTER.EXE in "Safe Mode with Networking"A8: Make sure you have Microsoft .NET Framework (at least 2.0) installed and fully patched.A9: Even also try to register at a friend, you only need some files from the Witcher folder, put them on a USB flash stick or something, you do not need Data & System folders, you do not need to install the game on your friend's computer. Just run REGISTER.EXE there, if it works ( and it did to a lot of people that could not register from their houses ) then export the registry keys on the registered computer: HKEY_CURRENT_USER\Software\CD Projekt RED and HKEY_LOCAL_MACHINE\Software\CD Projekt RED and import them in your game system. After this retry to patch.
