that's a known wrong positive for the Windows S-63 fingerprinter.
But we have no clue how to get rid of it - heuristics and as the Windows virus checkers will not accept messages about false positives if you don't buy their crap we just carry on.
A.: use a system with Linux
or OSX to download the fingerprinter
B.: tell Google
that they should not just copy messages of that type
C.: in the worst case we can mail you that executable
Out of couriosity: who tells you that they will not license
charts/cells for a valid IHO S-63 UserPermit?
Admiralty does, AHS does, ChartWorld does....
