Unsupported compression method [xzlib+srep+lzma2:ultra:64m:bt4:fb273:lc8:mc1000000]

I used this method to compress a game

Code:

xzlib+srep+lzma2:ultra:64m:bt4:fb273:lc8:mc1000000

but now the installer is unable to extract it
Can anyone help??

I mean what should arc.ini and cls.ini and tools to be included in the installer

The name used for compressor during compression in arc.ini must be same for decompression end too, for example :

xzlib+srep+lzma2:ultra:64m:bt4:fb273:lc8:mc1000000

Code:

[External compressor:xzlib]

header    = 0

unpackcmd = xtool.exe decode -t100p - - <stdin> <stdout>

if method is xzlib+srep+lzma2:ultra:64m:bt4:fb273:lc8:mc1000000

and it is set like this :

Code:

[External compressor:xtool_zlib]

header    = 0

unpackcmd = xtool.exe decode -t100p - - <stdin> <stdout>

The installer won't detect it. Set the same for lzma2, it uses 7z and use CLS-SREP for srep.

should my arc.ini look like this??

Code:

[External compressor:lzma2]

header = 0

unpackcmd = 7z x -txz -an -y -si -so <stdin> <stdout>



[External compressor:srep]

header = 0

unpackcmd = srep -mem512b {options} -d -s - - <stdin> <stdout>



[External compressor:xzlib]

header    = 0

unpackcmd = xtool.exe decode -t100p - - <stdin> <stdout>

Yes but make sure to use CLS-SREP for srep, just remove it from arc.ini.

Plus the commands may differ by version.

Use the same versions used during compression.

Side Notes : if it still doesn't work, explain more about your issue, such as which compressor was used etc and i will try to help.

Well yes, in some cases, for example on mp4 files.

Still it depends on cases.

I banned him and deleted his post, I also edited your post since you quoted what he posted ;)

EDIT: For everyone else, Carldric is referring to someone who posted crap advertising, thats why his post looks like it is random and doesn't make sense. :)
