Get the latest mod manager build for your platform. Verify integrity before install and use only official distribution channels.
Follow this Windows walkthrough after downloading the Thunderstore zip. Each step matches the official installer — version numbers in screenshots may differ slightly from the latest release.
Get R2ModMan the R2ModMan zip from an official source, open it in WinRAR or another archive tool, and click Extract To to unpack the files into a folder you control.
Open the extracted folder and double-click r2modman-Setup (the version number in the filename may differ). This launches the Windows installer.
When asked who the app is for, select Only for me for a standard per-user install (recommended). Choose all-users only if you need a system-wide install and can run as administrator. Click Next.
Review the destination folder — the default path under AppData\Local\Programs\r2modman works for most users. Use Browse to change it if needed, then click Install.
When setup completes, leave Run r2modman checked to open the app immediately, then click Finish. Select your game from the grid and create your first profile.
After installing the manager, pick your game from the grid, create a profile, and browse Thunderstore for mods. Risk of Rain 2, Valheim, Lethal Company, and dozens of other Unity titles are supported.
Keeping mods current is straightforward. There are two ways to update mods inside the manager:
You can also click the cloud icon on a mod card directly to update without opening full details — useful when updating one mod at a time after a game patch.
Updating one by one is recommended when debugging crashes — you can see exactly which mod changed. If updates still fail, check our troubleshooting guide.

R2ModMan is open source. The canonical package is published on Thunderstore under ebkr/r2modman. Source code is maintained in the r2modmanPlus repository by the same developer. This website does not host installer files; download buttons on this page will point to your chosen official URLs when configured.
When you download from official release pages, compare the published SHA-256 or SHA-512 hash against your local file using your operating system tools. On Windows, use CertUtil. On Linux, use sha256sum. Matching hashes confirm the file was not altered in transit.
Signed installers may be provided on some release channels. If a signature file is available, verify it with the developer public key before running the setup executable.
Mod managers interact with game directories, download community DLLs, and may use installers that trigger heuristic detections. R2ModMan is widely used with millions of Thunderstore downloads and is not classified as malware by the open-source community.
False positives are more common when downloading from unofficial mirrors. If your antivirus quarantines the app, restore only after verifying hashes from an official source. Add an exclusion only when you have confirmed file integrity.
