What specific (e.g., PIN block parsing, DUKPT derivation, EMV tag decoding) are you trying to accomplish?
Once you download the file (typically named BP-Tools_CryptoCalc_20.12.zip or bp-crypto-calc-20.12.exe ), always verify its hash. The legitimate SHA-256 hash for version 20.12 (as confirmed by multiple forum posts) is:
