Help when you need it.

1. Confirm you're using 64-bit Windows 10 or 11.
2. Download the EXE again from the official Download page.
3. Verify the file's SHA-256 hash against the one shown on that page.
4. Check whether Windows Security has reported a specific concern. The EXE is unsigned; do not disable security protections just to run it.

1. Use ASTRA V4.1.1 rather than the original V4.1 picker.
2. In Pro Studio, choose Activate license.
3. Select the full .license.json file you downloaded, not the EXE or a ZIP.
4. Check the expiration date. The public beta license expires November 3, 2026.
5. Restart ASTRA and verify the Pro label is still shown.

Earlier owner/demo licenses may use a different format. An unsupported license type warning means the file may not match the current activation format.

The Windows version can write a diagnostic log at:

%LOCALAPPDATA%\ASTRA Launcher\astra-diagnostic.log

Press Win + R, paste that path, and review the latest lines. Logs can contain your Windows username and local file paths. Remove private information before sharing anything.

1. Check that ASTRA has an internet connection.
2. Make sure automatic update checks are enabled under Settings.
3. Restart ASTRA or check the Release notes manually.
4. If update verification fails, use the manual official download instead. Never install an update whose signature or hash fails verification.

ASTRA keeps application entries, favorites, history and settings locally on your Windows PC, not on this website. Back up your collection using the app's export or backup features before making significant changes.

Removing ASTRA's portable EXE does not necessarily delete local data. Keep your saved JSON and backup files if you want to restore your collection later.
