Product Key Doesn't Work
Each major version of FileCenter (like "7.0, 8.0, etc.") requires a new product key.
If you try to, for example, install FileCenter 8 over a copy of FileCenter 7 or use a FileCenter 7 key when you install FileCenter 8, you'll get an error that your key isn't valid.
Solution: contact our Sales department for a new key. Note that this might require purchasing an upgrade.
