I downloaded from Microsoft! What is a CRC? I've tried redownloading and it
picks up on the download saved to my desktop??
Delete the download on the desktop.
CRC stands for Cyclic Redundancy Check. Years ago it referred to the
packet number and its reciprocal (totaling 256), that used to be
attached to the start of a download packet so Kermit or Xmodem (two
early download protocols) could detect a repeat of a previous packet.
This could happen when an ACK or NAK was misread and a packet was
repeated. (There was a lot of "noise" back then, so quite a few errors
in transmission.)
Today's reference to CRC is a misnomer, I believe, and should probably
be called a "Checksum" as that's probably what would be published: a
checksum showing the total of all bytes, possibly ANDed with 256, 65536,
or some other number.
Just my opinion.. some facts, some failing memory.
