- Missing DLL / failed to start: install the latest Visual C++ Redistributable (x64), reboot, and try again.
- Windows SmartScreen or Defender blocked the file: allow the PureDMA loader from an official download only. Do not run cracked or re-uploaded copies.
- Firewall / network errors: allow the loader outbound access so it can validate your license and fetch updates.
- Permission errors: run the loader as Administrator once, then retry a normal launch.
- DMA not detected: reseat the card, confirm firmware/cables, and verify the second PC sees the device before launching.
- False positive quarantine: restore the file from quarantine and add an exclusion for the PureDMA folder.
