Update 2026-04-05: Microsoft has resolved the false positive with our installer as of the antivirus definition 1.447.161.0.
TL;DR: If you use Technic Launcher on Windows, please switch to the new Windows installer: download it here. It installs the launcher together with the Java runtime it needs, gives us a much cleaner repair and update path, and is now the recommended way for Windows users to run Technic.
For a long time, the Windows Technic experience was mostly "download the EXE and go." That was simple, but it also meant installs could end up depending on whatever Java happened to already be on the machine, plus whatever old files were left behind from previous setups.
The new installer gives us a cleaner baseline. It installs the launcher, installs the matching Java runtime it needs, creates shortcuts, and makes the whole setup much easier for us to support long-term.
Why switch?
- No separate Java setup — the installer brings the runtime Technic needs with it.
- More reliable repairs and updates — if something gets out of sync, we have a much better path to fix it.
- A more normal Windows install — shortcuts and uninstall behavior work the way you'd expect.
- Better long-term support — this is the Windows setup we want users on going forward.
Already using Technic on Windows?
That's fine. Just close the launcher and run the new installer. In most cases, switching over should be straightforward, and once you do, you'll be on the setup we recommend for Windows going forward.
The older standalone Windows download is not disappearing overnight, but if you're on Windows, this is the version you should be using from now on.
