For my part, yes.
UltraArc is developed by Razor12911 and the credits are his (But someone keeps editing it, as this last version has removed certain features that I thought should be kept).
Only the script code (including ISPP code for the compressors included) that I created.
You may still have small parts of the original code Yener90 (CIU) and FreeArc example (Razor12911) in the Light Installer Script.
So even the script code is not entirely mine.
I just fully developed "COMPRESSOR_GUI.exe" and redid almost the entire "DiskSpan.bat" file.
For my part, you can use it, without problems, but I would recommend at least commenting some reference to the developers of the included software, such as UltraArc....

as you can see my other project, I always mention them. you can see them.

Always got his error
 

Hi,

I have compress the archives with SPREP and LZMA, with UltraARC that comes with the Light Installer but I always get this error when trying to run:

ISDone.dll
And error occurred while decompressing: Archiver header is corrupt!
Unharc.dll returned an error code: -14
ERROR: this is not FreeArc archive or this archie is corrupt

What i am doing wrong?

It seems to work normally here (using UltraArc method SREP+LZMA).
See on VIDEO if that's how you used it.
It is necessary to activate SREP in COMPRESSOR_GUI before compiling Setup.exe.

Ah, thx, i did not know that the record.ini should be in Light Installer folder. But it makes sense now. Btw great job on this :)

Light Installer Script 1.0.0.7
 

Added new Light Installer Script 1.0.0.7.
P.S: Now LIS is compatibility with DiskSpan_GUI tool.

I have a problem. I want to pack sims4 ... standard: srep + xtool + lzma2 or 4x4 ... whatever ... but for each reserve it stands at 1.2%. I kept all night, nothing moved, disckspan "goes to sleep".

I have compressed a lot of games this way, with different methods and never had this problem.
Do you know any solution?

Are you using DiskSpan_GUI that comes with LIS 1.0.0.7?

yes, last diskspan_gui from you

The version DiskSpan_GUI that is with Light Instaleler 1.0.0.7 is a little old.
You can download the latest DiskSpan_GUI together with the CIU source code HERE.
Download the CIU source code and extract the COMPRESSOR folder and place your setup.exe and setup.ico (created by Light Installer) in the "COMPRESSOR\Setup_Files" folder.

If it is another version you were using, test it with the current version informed, and let me know if it worked.

the same problem. diskspan_giu in CIU folder freezes at the same stage: 1.2%

I copied setup.exe and ico form light installer before

What method are you using?

xzlib+srep_new+4x4:b128mb:lzma:ultra:128m:bt4:fb27 3:lc8:mc1000000

srep xtool + lzma 4x4

always this same

I packed other games with this method without any problems

What game are you trying to compress?

I did a test here with a file folder is the method that you informed me is compressing and decompressing normally.
Perhaps some file, or file extension contained in the folder you are compressing is stalling the conversion.
Non-ASCII characters such as cyrillic in file names can cause errors (perhaps even crashes).

You can test using the XTool 2020 ZLIb.

other games are compressing.
The sims 4 is not compressed.
I always use the same method.
