Complete guide to activate retail UT3 on Steam
 

<for a feel good clean install perform first 3 steps>

- Make a copy of the UT3 folder.

- Right click on the backed up folder -> properties and make sure its NOT read only (make sure you apply changes to all sub folders too when prompted) .
The idea of making folders not read only is so that you can transfer file contents from one folder to another. If you make the folder not read only and if you check again and its read only, dont worry too much as long as you can copy the contents fully from 1 folder to another without any error message during the copy process

- Uninstall UT3.

- In Steam click on "My Games" menu and then click on the button "Activate a product on Steam".

- Follow instructions on screen and enter your UT3 retail key and Steam will correctly identify it and add it to your download list.

- Start the download and pause it after about 10 seconds.

- Then go into your steam home directory "\Steam\steamapps\common"

- You should see a folder called unreal tournament 3 (make sure this folder too is NOT read only) and within the folder you should see folders similar to that of the UT3 folder you copied in step 1.

- Optional Step: to be safe exit Steam.

- Now copy the contents of UT3 folder of step 1 into this "Steam\steamapps\common\unreal tournament 3"
OR
- If you did not perform the first 3 steps, copy the contents of UT3 into "Steam\steamapps\common\unreal tournament 3"

- Start Steam again if you had shut it down.

- Once that's done, in steam right click on the UT3 download you paused and select properties. In the last tab you should see a button called "verify integrity of game cache".

- Once cache has been verified steam will download additional files like DX9, Open AL, Physx, C++ redist and some additional game files. You should see these folders being created as download proceeds.

- The total size of download will be approx 450MB for v1.3 toSteam.

--------------------------------------------------------------------

Patch and Titan Pack Updates:

Steam will auto update to version 2.0 and install titan pack

OR

People can install retail patch and pack onto the Steam UT3 version 1.3. The installers will ask for UT3 directory location and once you show it the location it will patch it correctly. However you will need to verify cache integrity again and this time around Steam will download approx 350MB.

--------------------------------------------------------------------

If all goes well... all your settings, configs, etc should be transferred correctly.

PS: if you want to be a bit more studly try this pro move mentioned below instead of the copy and paste action.

Ah yes, junctioning worked for me. See this post by Sir_Brizz at BUF for info. Also, the junctioned folder needs "Read only" to be unchecked.

MAJOR NOTE: You don't have to activate the game on steam. You can still play on retail version (atleast for now). If you dont uninstall the game and proceed to activate the game on steam, you should have 2 copies of the game, the retail version and the steam version and you should be able to play them both.
