The UH 4.0 Self-extracting EXE installer is available below. You should save this file to a directory other than your totala installation.

Download UH 4.0 (Switch version, 10.9 MB)
Download UH 4.0 (TA:M version, 10.4 MB)
Download UH 4.0 (Zipped data files, 9.9 MB)

Installation is simple. After you finish downloading the file to whatever directory you choose, locate the setup exe and run it by double-clicking. This will launch the self-extracting installer and display this dialog:

IMPORTANT: If you try to run the setup and you get a message saying "Setup Error: Unable to initialize setup files," head to the Troubleshooting page for some possible solutions.

After you click Setup, the installer will extract the setup files to a temporary directory (usually C:\WINDOWS\TEMP), and after a few seconds delay it will launch the InstallShield setup. Typically, installation will only require clicking the Next button a few times, as the setup should be able to locate your TA installation and proceed.

If you have any problems with the setup, head to the UberHack forum of TA Universe, and we'll get it straightened out.

NOTE: Before you install UH 4.0, I recommend that you remove all other third-party UFOs and mods and restore your TA setup to an unmodified state. You can keep any maps you have, as long as those maps don't include third-party units. Setup checks your TA installation and will warn you if it detects that your REV31.GP3 file is not the original Cavedog file.

All versions of UH, including the various test builds, have a box on the title screen indicating their version. If your title screen has a box containing "UH 4.0" on the right, then you have the correct and current version of UH.

The Switcher includes a Readme.doc file that describes its workings in detail, but here's a preview of what it looks like and how it works. When you run the UH 4.0 setup, it places a Switcher shortcut called TA+UH on your Desktop and Total Annihilation menu. The Switcher EXE is a simple, one-dialog app:

When you run the Switcher it attempts to determine what AI and UH version you have active (if any). It also check to see what AIs and mods are available; choices that aren't available will be greyed out (like the "UberHack 1.1" selection in the example above). The Switcher also finds your current IP address (if connected), and the last multiplayer Host/Game Name you used.

To Switch to any available AI or UH setup, just click the radio button next to the selection you want. Switcher 3.0.4 works very quickly, because it renames files and directories instead of copying or deleting them. It does not modify your totala.exe in any way.

• The Host a Game button starts TA and begins the setup of a multiplayer game using the name you provide in the Game Name edit box.

• Click Join a Game to launch TA and search for a game at the IP that you enter in the Host IP Address edit box.

• Use Launch TA if you just want to play a Skirmish game.

• Click Readme to edit the included Readme.doc file, which includes these same instructions as well as a few additional notes.

The Difficulty tab changes your current Skirmish difficulty without your having to start a Skirmish game to save the value. Why would you want to change the Skirmish difficulty for a multiplayer game? Well, if you’re using AI players, their difficulty is assigned according to these rules:

• An AI running on the Host machine always uses the Hard difficulty.

• An AI running on a machine that has Joined will use the current Skirmish difficulty, so if you Join a game with your Skirmish set to Medium, an AI that you add to the game will use the Medium difficulty.

Yes. UH does not modify TOTALA.EXE in any way, and it does not make any changes to the original REV31.GP3 data file. Not everyone likes UH ... the most common stated reason is that some of the changes are just a little more than they're comfortable with. Even though the majority of the unit tweaks are small and subtle enough to go unnoticed, a few (Air-only AA, Freaker, Reaper, Warrior, Gimp, etc.) are substantial. In any case, you can safely remove the UH data files from your TA setup in a matter of seconds.

A small percentage of people who have downloaded the UH 4.0 self-extracting EXE have reported getting "Setup Error: Unable to initialize setup files!" message. If you see this error, there are some solutions on the Troubleshooting page that you can try.
