3 Way Compression, Masked Compression

[github]

Ok a simplier version to reproduce the problem:

Download Masked_Compression_v3.0_.7z and extract.

Put in a random file in pack folder for testing.

Try to run Advanced_Data_Arc.bat

with default packing command of

arc\Arc a -ma9 -ds -lc4096 -ld4096 -di -i1 -ep1 -ed -r -w.\ Setup-1.arc ^
-msrep:m3f:a8:l256+exe+lolz:d128m:mt2 "pack\*"

Packing is fine.

Try to unpack.

problem 1:

Arc_u folder has cls-lolz.dll and cls-lolz_x64.exe but not in Arc folder.
Guess when unpacking cls-lolz will be called, this cause the following problem of:

cls-lolz: Can't create read mapping

while trying to unpacking.
I moved cls-lolz.dll,cls-lolz_x64.exe out temporary to solve this issue.

Problem 2:

Arc_u folder has CLS-srep.dll and cls-srep_x64.exe but not in Arc folder.
This also create problem of

CLS-srep:can't create read mapping

while trying to unpacking.
I moved CLS-srep.dll and cls-srep_x64.exe out temporary to solve this issue.

Try unpacking again,
report error of

ERROR: archive data corrupted (decompression fails)******************************************** ***********************************

Decompressing is Completed

************************************************** *****************************

Upon checking the

-msrep:m3f:a8:l256+exe+lolz:d128m:mt2

The srep64.exe in Arc and Arc_u folder is not the same.
Tried to unpacking with the srep64.exe from Arc folder, will not unpack.
Tried to packing with the srep64.exe from Arc_u folder, will not pack.

It's a dead end
