This is an old version, but even running tenacity cracks (even if from a seemingly trusted person) is an unneeded security mess up as there is a leaked src of the newest version (as far as I know) and building it would be way safer, but most Tenacity cracks out there published by actual semi-known people/groups and not redistrubuted by random kids are safe anyway.
TL;DR Just build the src and if you really can't do that then run an already verified crack from somewhere other in this forum instead of believing this 15 year old random is trustworthy
