What I'm doing wrong?

--attack-mode 1 works differently between GPU and CPU versions.

From: https://hashcat.net/wiki/doku.php?id=combinator_attack

Combinator Attack Within (cpu) hashcat
Hashcat (or cpu hashcat, hashcat-cli*) does also support the combinator attack mode.
The only (and important) difference between combinator attacks within oclHashcat and hashcat is that cpu hashcat does the combination of the plains given in a single dictionary file (word list), while for oclHashcat you need to specify exactly 2 files.

This implies that one should specify only and exactly 1 (dictionary) file within the command line for hashcat (besides the hash file).

The combinator attack hence will combine each and every word within the single dictionary file.

Example:
hashcat-cli64 -m 0 -a 1 hash.txt dict.txt

So you'll need to drop one of the dictionaries from the command (or "uniquely" combine them into a single dictionary, Words3.txt):

hashcat-cli32.exe -m 2811 --attack-mode 1 Hash.txt Words3.txt --outfile recorver1.txt

And I'm not a boy.
