UltraARC for Inno Setup (Conversion Tool)

[senying]

how do i apply ZTool to UltraArc ?

i edit the config 0 in my method to this :
My Method:
tor = plz4+srep+delta+lzma

[External compressor:plz4,plzo]
header = 0
packcmd = ZTool e:{compressor}{:option} - -o - $$arcdatafile$$.tmp -o <stdout>
unpackcmd = ZTool d:{compressor}{:option} - -o - <stdin> <stdout>

it gives : "Failed to create Data1.Bin"

i already copy the ZTool.exe and all the .dll it needs to the Resources folder
