Pojav Launcher is not yet supported due to drawbacks (long installation process, high energy usage, performance may not be better etc), but is being considered.
ATLauncher is currently not supported simply because the interface is confusing and complex. There have been discussions with its developer to improve this and it may be considered in the future.
To migrate to Prism Launcher (a safe fork of PolyMC), follow these instructions:
- 1.Uninstall PolyMC
- 2.
- 3.Launch it and pay attention to the prompt you get:
- 1.It looks like you used PolyMC before. Do you want to migrate your data to the new location of Prism Launcher?
- Click
Yes
and the migration will complete.
- 2.It looks like you used PolyMC on Windows before. Do you want to migrate your data to the new location of Prism Launcher?
- Click
Yes
and the migration will complete.
- 3.Old data from PolyMC was found, but you already have existing data for Prism Launcher. Sadly you will need to migrate yourself. Do you want to be reminded of the pending data migration next time you start Prism Launcher?
- Click
No
and follow manual migration instructions below.
- 5.To run the modpack, double click the Fabulously Optimized icon
- 1.Close Prism Launcher
- 2.Go to one of these directories according to your operating system:
- Portable (Windows/Linux):
PolyMC/instances
- Windows:
%APPDATA%/PolyMC/instances
- macOS:
~/Library/Application Support/PolyMC/instances
- Linux:
~/.local/share/PolyMC/instances
- 3.Select all the files and folders in the instances folder, right click on one of them and select
Copy
- 4.Open Prism Launcher, click
Folders
, thenView Instance Folder
- 5.Once your instance folder has opened, right click anywhere and select
Paste
- 6.Close Prism Launcher and reopen it, your instances should be there
- 7.Sign in to your accounts, configure Prism Launcher to your preferences
TLauncher is malware, so it will never be supported by Fabulously Optimized. It is highly recommended to reset your entire computer, then come back to this page and follow install instructions for any supported launcher.
Any launchers that let you run the game without having purchased it first are not supported.
There is a legitimate way to obtain Minecraft for cheaper: get a giftcode from a trusted reseller. After that, pick any supported launcher from this page and enjoy the game!
Technically you can install it in some other launchers that support CurseForge or Modrinth modpacks or in any launcher by following the vanilla instructions. However, please do not ask for support here if you use an unsupported launcher.
Some users have experienced interest in using FO with other, content-focused modpacks.
While it is theoretically possible, this is not advised:
- mods may have conflicts
- neither FO or the other modpack will be able to support you
Fabulously Optimized is not compatible with any "game clients", including "hacked clients" and "PvP clients". Use normal mods instead!
Fabulously Optimized is currently based on Fabric, not Quilt. It may run on Quilt, but it has not been tested and is not currently supported to ensure all mods work reliably. If you use it, do not ask for support in FO's Discord, but rather Quilt's Discord.
If there becomes a need, Fabulously Optimized will move to Quilt overall and then it will be fully supported. Read more on issue #257.
