A genuine RadiAnt DICOM Viewer key is typically a 5-part alphanumeric code (e.g., XXXXX-XXXXX-XXXXX-XXXXX-XXXXX). Common mistakes:
Fix: Re-enter the key manually, or copy it directly from the email sent by Medixant.
Search results for "RadiAnt DICOM Viewer activation key fixed" often lead to YouTube videos or sketchy Russian forums promising a keygen.exe or a fixed settings.cfg file.
Here is the harsh reality of "fixed" cracked keys:
Do not use a keygen. The "fix" for a cracked copy is uninstalling it and running Malwarebytes.
If none of the above works, the key is not broken—your situation has changed. Email support@radiantviewer.com with:
Legitimate users receive a response within 24-48 hours. They will issue a new activation key or a license reset tool.
Sometimes the problem isn’t the key, but the local database. If you see random crashes or "Activation lost" after a system restore:
The Fix: RadiAnt licenses are per-user, but many clinics buy Team licenses (3-5 seats). If you get this error, you have exceeded your seat count.
The Fix: Many users confuse a perpetual license with maintenance. A standard RadiAnt Pro license is perpetual for the version you bought (e.g., v2023). However, if you upgrade to v2024 without an active maintenance plan, your old key will show as "Invalid for this version."
If you want a permanently fixed setup that never asks for a key again, follow this legal workflow:
Step 1: Get a legitimate key.
Step 2: Generate your Hardware ID.
Step 3: Bind the key.
Step 4: Harden the key (Prevent future "FIX" needs).
Step 5: If all else fails – Contact Support.
RadiAnt’s support team (Poland-based) is notoriously responsive. If your key is "broken" due to a server migration, email them your HWID and receipt. They will send you a manual_unlock.bin file within 4 hours.
