3 Way Compression, Masked Compression

[github]

Thank you.
While running with administrator privileges those two errors are gone.
With the example command line to compress and decomperss works.

The next question is , what confused me for the last time, is
if I disable cls-lolz.dll and declare the method in arc_u\arc.ini:

[External compressor:lolz]
header = 0
packcmd = "lz\lolz_x64.exe" {options} $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd = "lz\lolz_x64.exe" $$arcpackedfile$$.tmp $$arcdatafile$$.tmp

This is the same definition in the compressing process. But the decompress will fail with


not an SREP compressed file.


Is it requied to use the cls-lolz.dll for any lolz compressed file?


Same thing happens to srep. If I disable cls-srep.dll and declare the method in arc_u\arc.ini:

[External compressor:srep]
packcmd = srep64 {options} $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
unpackcmd = srep64 -d -s -mem3072mb - - <stdin> <stdout>

This is the same definition in the compressing process. But the decompress will fail with


ERROR: archive data corrupted (decompression fails)


Is it requied to use the cls-srep.dll for any srep processed file?

I thought cls dlls are optional to use, not mandatory? That's why last time when I moved out the cls files, it ends up with
ERROR: archive data corrupted (decompression fails)
