Ask yourself "How critically important is this 'corrupt' CRC error file is...to your computer's operation?"
Then, firstly, RENAME it.........and download it, again!
If problem still exists, contact the Web-site from where you got it.
Inform them......of the persisting problem.
If it comes good the 2nd time around, the chances are that you've just had a 'bad download'.
If this is the case,you're basically....'crying over spilt milk', yourself having the intelligence of a complete moron!
Is your Internet Time...so critical that you CAN NOT afford......to do another download! (To verify the problem!.....one way or the other!)
Will your computer stop 'functioning'....altogether!, because of this so-called 'corrupt CRC file'?
(I doubt it! Which does make you the 'complete moron'!)
There's always another Program out there.......that is very likely....to do a better job of the Task you want the 'offending software'...to do!
Too lazy...to do your own exploring, well, it's certainly more a reason to 'classify' your moronic status.
