Download AstraBrew Launcher

The .exe installer is recommended and creates Start menu entries plus an uninstaller. A ZIP with portable in its name is the portable build; extract it and run the application directly.

After confirming the file came from the official AstraBrew GitHub Release:

1. Choose "More info"
2. Verify the application name and release source
3. Choose "Run anyway" to continue

Download the installer again to rule out an incomplete file, then check the following:

1. Confirm the system is 64-bit Windows 10 or later
2. Try running the launcher as administrator
3. Confirm the installation directory has read and write permissions
4. If the issue remains, include logs when opening an Issue or asking in the community group
