Do i have to change installers, or can i simply edit something? (Compression issue?)
 

This has to do with UltraARC, but also with the installer I usually use.

I compressed a 2.84 GB game to 1.68 GB, which I am perfectly fine with. I used these settings:
Precomp, LOLZ, SREP, and LZMA.

The installer I am using is this by Rinaldo:

I get these errors:

"Not an SREP compressed file"
"Unarc.dll returned an error code -2, unsupported compression method"

I am assuming not all installers that are posted here can do certain compression combinations, I just wanted to finally try out UltraARC since it gave me better results then normal FreeARC.

Would I have to try out a different installer, or is there something I have to add or drag and drop? If its the first, then what would you prefer? If its the second, what would i add?

Now, if i just do Precomp + SREP with UltraARC, i just get this error:
"Incompatible compressed data format"
Is this fault on UltraARC? How do I do precomp + srep on normal FreeARC if thats the case? Everywhere i look, it literally just has people that say can do it, but not show how to actually apply it.

First of all dude...
Srep mean super reflate , it preprocesses the data for the final tool or finishing one.
Lolz or lzma is a finishing tool (use anyone of them)
And the compression method is like

Precom (like Precom or ztool or xtool)+srep+Lzma(or lolz)

I'm not a special or expert in doing ultraarc thing..

But give it a try using Precom+srep+lolz or lzma

And in arc.ini of unpacking time, if u use cls-srep.dll with .exe (cls one not like srep.exe) u won't have to add any unpacking parameter but surely do use parameters of other tools (lolz either don't require unpack parameter)

#as well as you'll have to add the tools in unpacking section of the setup.exe ( you won't have to change any installer)

Okay, thanks for the definitions and usages of SREP/LOLZ.
Tried Precom+Srep+Lzma and I still get an unarc.dll error, oh well. Might just have to stick to normal FreeARC and deal with the little compression I get.

Wish u good luck and nice moments
