We have had that issue come up today as it pertains to running the financial statements:

"Adagio Financial Reporter requires adfiler64.dll 1, 1, 22, 257 or later."

So you are saying this is AV related and to mark as safe with their AV?

They run all other modules (including Ledger) without issue only on the financial reporter. FWIW.
