RO & RP 1 Express Installation for 1.12.3

§1: Preparing for Installation

1. Install a new copy of KSP 1.12.3. Do not try to install on top of your old modded KSP.
   • In Steam, select 1.12.3 by selecting 1.12.3 in the beta versions list.
   • If you purchased the game through the KSP Store, re-run KSPInstallerx64-1.12.3.exe to create a fresh copy.
2. Copy everything in your Steam install directory to a new directory that you'll use for RO. You may want to remove stock saves from the new directory that you've copied things into.
3. Download CKAN and point it at your new KSP 1.12.3 installation.

§2: Known issues

This list contains bugs and issues reported by you, the community. Feel free to edit this section if you find bugs/issues.

• SXT parts are missing textures, which can be fixed by running the Windows_CopyTextures.bat in the SXT folder
• EVE doesn't load clouds over Earth as displayed in the main menu. This is normal and expected.
• If your game freezes right before loading the main menu, give it time. If it persists more than a few minutes just close it and launch again.
• If you have a Linux installation, you have to start the game from the local game directory, or the game will pick up the wrong physics files (resulting in procedural wings overheating at launchpad and other issues)
• The Persistent Thrust mod can cause some engines to not produce any thrust. Avoid it.
• KER can cause random crashes in the flight scene. This is usually accompanied by RCS exceeded loop count logspam.
• Parallax will indicate it is not compatible with the current version of KSP. This is fine, and it will work as expected.

§3: CKAN Popups

• "The following mods have had their metadata changed since last update": Just click "Yes", it will complete very quickly and have little effect.
• "Module Ferram Aerospace Research Continued wants to overwrite the following..." Just click "Yes". It should be fine.

§4: Main Installation

1. Via CKAN, select search for and select Realistic Progression One (RP-1) Express Install.
2. Press green "Apply changes" button to switch to the Changeset tab.
3. Click Apply again to confirm.
4. You will be presented with a set of Recommended mods. These are the mods we recommend installing with RO/RP-1 and thus they default to being selected. You may, however, choose to deselect any you don't wish to install, though you are encouraged to leave them at the default values. When done, click Continue.
5. You will be presented with a choice of graphics level. Choose based on your computer's power level and memory. Medium should work for all but the slowest computers, or those with less than 8GB of memory. If you have 16GB of memory or more and a reasonably fast CPU and GPU, select High.
6. Click Continue again and all your mods will download and install. NOTE this will take some time, especially for the High-Res choice which involves multiple GB of downloads.

§5: First Launch of KSP

1. When CKAN is done installing, launch KSP.
2. Your first launch of KSP will take a very long time, and will appear to hang a few times, especially when the progress bar says Loading Expansions. This is normal; a first launch involves creating cached versions of the new planets and various other first time tasks, along with ModuleManager creating a cached copy of all config changes.
3. Once you make it to the main menu, go ahead and set up your settings the way you like. Lastly, create a test sandbox save and poke around to make sure that everything is working.

§6: Next Steps

Congrats, you're done. Here's what you should do next:

1. Proceed to New Career Setup if you are playing RP-1.
2. Scroll back up and locate the wiki sidebar. The "Getting Started" section contains a wealth of information for help and instruction.
3. If it's your first time playing RP-1, read the tutorial and the FAQ.
