UltraARC for Inno Setup (Conversion Tool)

[Atakanbasturk]

Guys, I'm new in UltraARC, I edited Config0.ini and my Masked Compression settings:

<Masked Compression>
MASK = srep:m3f+XZ/$binkpack=BPK/$mscdolid=MSC/$deflate=xZlib:erecomp:t75p:zlib+srep:m3f:l256+X Z/

I am choosing only MASK option under FreeARC under Options tab(and fill other tabs of course) but program says Failed to create data1.arc.

If I select other choices like Precomp, MSC, SREP etc., program starts and use chosen options. It's not using MASK option. But I don't want to use that options, I just want to use MASK option(my codes in config0.ini). What am I missing?
