HELP regarding creating repacks

[wrathma]

I have tried making repacks of small games which dont need to be cracked. But everytime i had some issue or i couldnt understand something so i just dropped it.

Right now im trying to make a self extractable repack of a 700 MB game. I used DiskSpan Gui and compressed it to 340 MB using the predefined compression.

XTool 2020 (zlib) + SREP + LOLZ

Then I extracted the dll and copied everything to Include folder of Simple Installer Script and compiled it with required arguements such as name,size etc. And moved the compiled exe to diskspan folder where there is the compressed game.
But after executing the installer, it throws an error saying Unarc returned error code -2, unsopported compression. Need guidance now. Thanks in advanced.

Edit:
After some tweaking the installer now says data corrupted -


My Include folder looks like this -

ARC.INI
CLS-DISKSPAN.dll
CLS-LOLZ.dll
cls-lolz_x64.exe
CLS-SREP_NEW.dll
CLS-SREP_NEW_x64.exe
CLS-SREP_NEW_x86.exe
CLS.INI
FACOMPRESS.DLL
FACOMPRESS_MT.DLL
UNARC.DLL
XTool\

And XTool folder -

hif2raw_dll.dll
liblz4.dll
libzstd.dll
lzo2.dll
preflate_dll.dll
raw2hif_dll.dll
XTool.exe
zlibwapi.dll
