TWOELV, Whyyyy Lzma2, "CMD Viper Edition" does not use the name LZMA2, but with 7z is compression line
"a -txz -an -mcrc=0 -m1=lzma2:d192m:fb=273:mf=bt4:mc=999999:lc=4:lp=0 -mmt=2 -mx9", the LZ77 algorithm is LZMA 16.04 with this
"-a1 -d27 -fb273 -mc100000000 -lc8 -lp4 -mfbt4 -mt8"...
so you have to delete this from INI files ...
Code:
[External compressor:Lzma2]
header = 0
unpackcmd = 7z x -txz -an -y -si -so <stdin> <stdout>

Code:
[External compressor:7z]
header = 0
packcmd = 7z a -txz -an -mcrc=0 -m1=lzma2:d450m:fb=273:mf=bt4:mc=1000000:lc=4:lp=0 -mmt=4 -mx9 -si -so <stdin> <stdout>
unpackcmd = dec x -txz -an -y -si -so <stdin> <stdout>
And finally uses this method and try ...
"pzlib+srep64+7z"
EDIT : Tested and functional out with the said method, two in bin format archives with your password, let me know if you have solved, otherwise tell me if you submit your work here or in private ...ciaoo
