Did you mean to write 1962s Crimen Sollicitationis?
If you did the difference is quite simply one takes place after the act of solicitation and one takes place prior to the act of solicitation.

The 1922 date was not a mistake, but I stand corrected on the spelling. I believe they are the same document, wherein the 1922 version was issued in Latin, and the 1962 document was an official (is that the right word?) translation of it. See this post for my understanding of the relationship between the two.
