srep / srep64? help me

[fabrieunko]

hello currently I use this method to compress my files

arc a -lc8 -ep1 -ed -r -hp1234 -w.\ C:\Games\TDF-Setup-1.bin -msrep+lzma:a1:mfbt4:d256m:fb128:mc1000:lc8 "C:\Games\Tour de France 2021\*"

with the following arc.ini

[External compressor:srep]
;options  = l%d (minimal match length, default=512)
header = 0
packcmd   = srep {options} -a1 -m5f $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd = srep -d $$arcpackedfile$$.tmp $$arcdatafile$$.tmp

[External compressor:precomp]
header = 0
packcmd   = precomp -slow {options} -o$$arcpackedfile$$.tmp  $$arcdatafile$$.tmp
unpackcmd = precomp -o$$arcdatafile$$.tmp -r $$arcpackedfile$$.tmp

how to use srep64.exe? what should be changed?

I have trouble understanding and finding the information to do this ..
