In order to play X-Wing Vs. TIE Fighter online, you need to consider the following steps.

1. Install the game - Copy the game files
2. Apply patches - Get necessary updates, files etc.
3. Networking - Port forwarding and firewalls
4. Set up Voobly - Enter the online gaming lobby to find opponents

You can install X-Wing Vs. TIE Fighter using the stock installer from the CD.

You can install X-Wing Vs. TIE Fighter using the stock installer from the CD.

You have to run the game in compatibility mode for Windows 98 and as an administrator, which can be done by right-clicking (“Properties”) the following files

 xvstie.exe
 Z_XVT__.EXE

Unfortunately the stock installer that comes with the XvT CD won't run in a 64-bit operating system. Basically you have two options.

The first and most option is to install X-Wing Vs TIE Fighter is to

1. Copy the game files manually. You can use any old installation for that, regardless on which operating system you ran it there. If you don't have the files lying around anymore. Ask another XvT player in the lobby.
2. Set up registry manually

Having done that, you have to run the game in compatibility mode for Windows 98 and as an administrator, which can be done by right-clicking the Files

 xvstie.exe
 Z_XVT__.EXE

Properties → Compatibility tab → Tick the “Run as an Administrator” check box and set the compatibility to Windows 98. Here's some official documentation from Microsoft for it.

The second and more complicated option you have is to forge a 64-bit compatible msi installer version for the XvT CD.

In this case you have some extra work to do, because Windows 7 systems are incompatible to the old 16-bit installer provided by the XvT disc. So what you need is a modified version of the installer by Markus Egger. All the documentation is found there, so we don't provide any support for it here.
