Rose is a free, open-source skin changer for League of Legends. LTK Manager is the League Toolkit team's mod manager for fan-made skins. Most people searching "Rose LTK Manager" hit the same wall: Rose asks for two patcher files on first launch, and those files only come from an LTK Manager install.
The LTK patcher is those two files, ltk_patcher_host.exe and ltk_patcher_dll.dll. League Toolkit ships them inside LTK Manager, and they apply mods to League when the game loads.
Fast answer: Install LTK Manager from its official GitHub release. Install Rose. On first launch Rose opens its tools folder; copy ltk_patcher_host.exe and ltk_patcher_dll.dll from your LTK Manager install into that folder. When a new League build passes the patcher's end-of-life date, Rose tells you, and you update LTK Manager and copy both files again.
Everything below comes from the two projects' own READMEs, LTK Manager's source code and Riot's support pages, all checked on 30 September 2026. At that date the current releases were Rose 1.4.4 (30 September) and LTK Manager 1.24.0 (29 September).
Get both installers in one place. Our Rose, LTK Manager and LTK patcher download page streams each installer from its project's latest GitHub release when you click. The file passes through unchanged, so League Toolkit's code signature stays intact, and you don't need an account.
Why does Rose need LTK Manager?
Rose's README: "Due to DMCA restrictions, Rose cannot distribute the LTK patcher." The patcher is the part that loads skin files into the game when a match starts. League Toolkit ships it inside LTK Manager, under its own licence, so you take it from there.
The two projects have different authors and do different jobs.
How do you set up Rose with LTK Manager?
The whole setup is two installers and one copy. Step through it here, with the download buttons on the steps that need them:
Installing Rose
Step 1 of 5
Install LTK Manager first
Rose can't ship the LTK patcher, so its README has you take ltk_patcher_host.exe and ltk_patcher_dll.dll from an LTK Manager install and copy them into the tools folder Rose opens at first launch.
Download LTK ManagerInstall and launch Rose
Run the installer as administrator, then start Rose from the Start Menu. It sits quietly in your system tray from here on.
Pulled fresh from Rose's own GitHub releases every time this page loads — never a stale mirror, never a version behind.
Open champion select as usual
Rose's Pengu Loader plugin unlocks every skin tile for preview. The grid looks the same whether you own one skin or all of them.
Pick a skin and lock in
Hovering or locking a skin sends that choice to Rose over a local connection. Nothing is injected yet at this point.
Load into the game
Rose swaps in the skin's files during loading screen, using the DLL from step one. You spawn already playing it.
The same steps as a list, with the details the READMEs add:
- Install LTK Manager. Download the -setup.exe from its GitHub releases or from our LTK Manager download page, run it, and open the app once. It looks for your League install on first launch; if it can't find it, you pick the game folder yourself.
- Install Rose. Download Rose_Setup_1.4.4.exe (or newer) from Rose's releases, run the installer as Administrator, then start Rose from the Start menu or the desktop shortcut.
- Copy the patcher files. On first launch Rose asks for the patcher and opens its tools folder. Copy ltk_patcher_host.exe and ltk_patcher_dll.dll from your LTK Manager install into it.
- Pick a skin in champion select. Rose's client plugins unlock the skin previews. Hover a skin, and Rose applies it when the game loads.
Where are ltk_patcher_host.exe and ltk_patcher_dll.dll?
Both files sit in the LTK Manager install folder, next to the app itself. In LTK Manager's source, the two binaries live in src-tauri/resources, and the build config copies that folder into the root of the install. The installer does a per-machine install and only accepts a folder under Program Files, so look under Program Files\LTK Manager.
Don't download the two files on their own from another site. LTK Manager's patcher licence says League Toolkit code-signs its official builds, and anyone who repackages them must strip that signature. LTK Manager's Diagnostics page checks that signature, so a copy from anywhere else can fail the check. The only copy League Toolkit vouches for is the one its installer puts on your disk. If yours is missing, reinstall LTK Manager from the latest release; that is the fix LTK Manager's diagnostics code suggests.
How to fix the "LTK patcher outdated" error in Rose
Update LTK Manager, then copy both files into Rose's tools folder again. Rose's README explains the error: the patcher "stops working with game builds released after its end-of-life date", and Rose then tells you to update LTK Manager and replace the two files.
LTK Manager updates itself: it checks for new versions and shows you what changed before it installs one. Once it is on the new release, copy both files again, not only the DLL.
Fixing an LTK patcher that won't start
Open the Diagnostics page in LTK Manager. It checks your machine and your game install, including whether the patcher DLL is present, whether its signature is valid, and whether another process has the file locked. Its own check names Vanguard's vgc.exe as the process that most often holds it.
If Diagnostics doesn't solve it, LTK Manager writes a log to %APPDATA%\dev.leaguetoolkit.manager\logs\ltk-manager.log. The project asks you to attach that file when you open an issue on GitHub. For Rose problems, Rose's GitHub issues are the place.
A few limits from the READMEs save you a search:
- No Mac or Linux. Both tools run on Windows 10 and 11 only. LTK Manager lists macOS and Linux as planned.
- Garena and some Asian servers. LTK Manager supports Riot-operated servers; it does not officially support Asian servers or Garena, and says they "may run into issues".
- cslol-manager users. LTK Manager's default Start button works like cslol-manager's: start the patcher, then open League from the Riot Client.
Rose features beyond the skin swap
Rose's README lists more than the skin swap. Rose never injects a skin you already own. It supports chromas and skins with multiple forms, such as Elementalist Lux and Spirit Blossom Morgana. It loads custom mods too (.fantome, .zip and .modpkg), including maps, fonts and announcers.
Party Mode lets friends who run Rose see each other's picked skins in game, through a relay with room for 10 people. Rose only changes files on your own machine, so players without Rose don't see your skin.
Rose also sends a startup ping and a 15-minute presence heartbeat with a random installation ID and the app version. The README says you can switch this off with ANALYTICS_ENABLED = False in config.py.
Is Rose safe to use?
No one outside Riot can tell you that, and Rose doesn't claim it. Its own disclaimer: "Riot Games does not allow custom skins that reproduce its real skins, which is what Rose does. Use Rose at your own risk."
Riot's third-party applications policy says the same from the other side: "we reserve the right to take action against applications that allow the use of our assets for free (often referred to as skin hacks)." LTK Manager loads fan-made art rather than Riot's skins, and still tells you to use it at your own risk.
The comparison of free and paid skin changers, and why fan-made skins and unlocked Riot skins sit in different places in Riot's policy, is in our custom skins guide.
Rank, coaching and duo on Pairly
A skin changes what your champion looks like on your screen. Your rank is the part everyone else sees. If you'd rather climb than grind, Pairly's LoL rank boost prices your current and target rank up front, and LoL coaching puts a Master or Challenger player on a stream with you instead. Looking for someone to queue with? The Duo Finder is free.

Frequently asked questions
What does Rose ask for on first launch?
The LTK patcher. You install LTK Manager and copy ltk_patcher_host.exe and ltk_patcher_dll.dll into the tools folder Rose opens at first launch. Without them, Rose can't apply any skin.
Who makes Rose and LTK Manager?
Different people. Rose is a skin changer by Alban1911. LTK Manager is a mod manager by League Toolkit. Rose borrows the patcher that LTK Manager ships.
Where do I put the LTK patcher files for Rose?
In Rose's tools folder. Rose opens it for you on first launch and asks for the two files.
Where does LTK Manager install the patcher?
In its install folder, next to the app. The installer only accepts a folder under Program Files, so look in Program Files\LTK Manager.
Is a patcher DLL from another site the official file?
No. Under its licence, the signature may appear only on unmodified LTK Manager releases and on copies from distributors League Toolkit approves in writing. Get both files by installing LTK Manager from our Rose and LTK Manager downloads page.
How often do I have to copy the patcher files again?
After every League build that comes out past the patcher's end-of-life date. Rose tells you when it happens; update LTK Manager and copy both files into Rose's tools folder again.
Do I have to keep LTK Manager installed?
Rose only asks for the two files. Keeping LTK Manager installed makes the next update easier, because the app updates itself and you copy fresh files from the same folder.
Is Rose free?
Yes. Rose is free and MIT-licensed. Its README warns that if you paid for it, you got scammed.
Does Rose work on Mac?
No. Rose and LTK Manager both run on Windows 10 and 11 only.
Can other players see my Rose skin?
Only friends who also run Rose, through Party Mode. Everyone else sees the skin their own client loads.
Can I get banned for using Rose?
Riot says it reserves the right to act against "skin hacks", and Rose's README says its developers aren't responsible for "account suspensions or bans". No one can promise you won't be.
Is LTK Manager the same as cslol-manager?
LTK Manager is the League Toolkit team's successor to cslol-manager, and cslol-manager's README points to it. Both installers are on our LoL skin tools download page.
