@ZAZA4EVER .... Well, many times be taken for granted but have you tested the command line archive?
Code:
Arc.exe t -i2 Archive
Also you have tried with this replacement in the decompression arc.ini
Code:
unpackcmd = srep64.exe -d $$arcpackedfile$$.tmp $$arcdatafile$$.tmp
or
unpackcmd = srep64.exe -d -s - - <stdin> <stdout>
Code:
unpackcmd = ztool198.exe d:pzlib:t0:cm16mb:b128kb:f - - <stdin> <stdout>
Code:
[External compressor:lolz_x64]
header = 0
unpackcmd = fazip.exe -i0 decompress:lolz <stdin> <stdout>
Logically fazip.exe and relative *.dll must be compiled and loaded into ISS.
EDIT TEST
with some fix in ISS the method extracts perfectly, use "fazip" and the "ztool198" version and see that you solve.
