So that's a TrID result?

What about translating the AutoHotkey help file? Have fun!

Sorry, what "AutoHotkey help file" are you refering to?

Nope, a formula: f(x)=8+512*x

I thought you want something to waste your time on?

Help file is part of the archive, it's only 1 MB.

in MA 1.2
If SkipSfxHeader=0 uses IDPOS.
If SkipSfxHeader=1 try calculate size of SFX. ID search by Sfx_size+IDPOS. if sfx not packed exe-packer calculation for PE-EXE success. For some exe-packer succes, for some not.
In 1.3 search algoritm changed.

The string vserd has mentioned is:
4 bytes plus NullsoftInst

The point is that it is easier to search for "NullsoftInst" than to search for "ï¾ÞNullsoftInst", you see?

For Manual search and detect IDPOS I use "NullsoftInst", but for MA more best if ID same as used for detect in command-line utilites for archive.
I get ID=EF BE AD DE 4E 75 6C 6C 73 6F 66 74 49 6E 73 74 from source of 7-zip.

The correct string doesn't work with MultiArc... Obviously it has a problem with "strange" characters.

Edit: Ah crap, of course the IDPOS values have to be lowered by 4 then, that's why it didn't work.

New version using the correct ID:
NSIS_using_7-Zip_4_40_and_up.zip

FYI:

Strangely the standalone command line version 7zA.exe doesn't seem to support the same files as 7z.exe (both 4.41b).

There's no 7za.exe of version 4.41.
7za.exe was a command line version of 7z, while GUI-version was 7z.exe.
Now 7z.exe is command line, while 7zG.exe is GUI.

Nope. Look here.

7z.exe is (and was) a console version but it needs the format and codec DLLs.
7za.exe is (and was) a standalone console version with no further dependencies on DLLs.

Oops, really...
But I remember that 7za could be downloaded from the main page, while today it can't be. So I decided it had become extinct.

Where can I get "your" IETotal?

2all
With the addon we have now the new 7z version 441 doesn't show script inside an archive. There's no [NSIS] file inside.

I searched this old IETotal version months ago too.
Could you please upload it to Rapidshare icfu?

And still a question, why do I get no mail if someone
sets a new post into this thread since two days?

@XPEHOPE3KA & TychoBarfy:
Do you see the button WWW under my postings?

Ah, thanks. Seldsome, now I got a mail again.

I have uploaded the archive to totalcmd.net after vserd has dropped me an email, including credits, changelog, etc...:
