Failed to extract file.

[Reminiscence0]

Hello. I'm trying to extract cab files from an InstallShield installer.
Link: https://www.kodensha.jp/sstec/update/jb/jb7up.exe
First, I extracted the executable using isx.exe. I got data1.cab, data2.cab, etc.
Then, running "unshield -d output x data1.cab", I got a error message:
extracting: out/JCMAIN/jcmain.DDB
Failed to extract file 'jcmain.DDB'.Run unshield again with -D 3 for more information.
Am I doing something wrong? Please give me some suggestion. Thanks.

So what output do you get when your run with -D 3 ?

[twogood]

You could also try the -O parameter, it means Use old compression

[Reminiscence0]

Option "-D 3" outputs lots of messages flashing away quickly.
Option "-D 2" outputs "[unshield_file_save:749] Decompression failed with code -3.".
I tried extract with"-O", but the program crashed right after the line " extracting: out/JCMAIN/jcmain.DDB".

[twogood]

code -3 usually means that -O should work :)

But I'll have to check these myself then.

[Reminiscence0]

I checked the version of I'm using is "1.4". And the latest version in Github release is "1.4.3".
Could this be the reason I'm getting errors? If it is so, where can I download the latest version?
The "download page" link in readme expired and automatically deleted.

The Windows version of unshield is a mess, sorry about that.

[twogood]

I will try with the latest code.

There are some fixes regarding character encoding that might be relevant when you download from .jp?

[Reminiscence0]

It might not be the problem of character encoding. This error file contains only ASCII characters ("JCMAIN/jcmain.DDB"), and all the other files with similar name ("JCMAIN/jcmain.DIC") extracted with no error.
Anyway, thanks for your investigation in advance :)

But if you are on Windows why not just run the installer?

The file I'm trying to extract is an update file installer. I reinstalled the OS a year ago, and some registry of installation gone with the previous OS. When I run the updator, it shows me the program is not installed. I also can't found the install disk of main program which I bought over six years ago. So I want to extract the update files and patch them manully.
