They are both Acresso and/or InstallShield v16.0.0.328 installers with an msi-based install.
  IsXunpack.exe doesn't work, either.  However; Setup_0.112.exe /b"C:\temp" works in Command Prompt.
  Note that i have not tried this with UE 1.6.1.58.
Please pass this on to gora (if not already known) if you have time & the desire to do so.

BTW, the installer with "SendTo" worked well.

This returned the following log, and no files output to the desired location.

Hold the press,

This worked like a lucky-charm when placed in the same folder as setup.exe.  (IsXunpack.exe from C:\Program Files\Universal Extractor\bin)  Unfortunately, this doesn't preserve original file dates either.
  I wonder why it is that UE doesn't work for this.  Perhaps gora knows.
  I will make note of any other driver installers i find that resist extraction; to aid the UE branch.

Tried /b<subfolder> switch but this only works on InstallShiled installers with msi base install

I understand that it is an 'exe and that it won't work with IScabVu, just thought i would make mention, though.
So far, i have to chase down the extracted folders in %temp%.  It doesn't seem to like me working with a package meant for win7 on XP from the log file in %temp%.

Here is something you guys might find useful, It comes with InstallShield (used to extract drivers/files from installers with data1.cab/hdr files)

Here is a link to the installer, I extracted the files from InstallShield 2012 Spring w/ SP1 (may also require Visual C++ 2008)

Download: http://www.wincert.net/forum/index.php?showtopic=9782

For unattended install

Passive:
<installer>.exe /SILENT

Quiet:
<installer>.exe /VERYSILENT

Other options:
/NOICONS
Instructs Setup to initially check the Don't create a Start Menu folder check box on the Select Start Menu Folder wizard page.

/COMPONENTS="!help"
Do NOT! install "Help files" components. (If a component name is prefixed with a "!" character, the component will be deselected.)

/TASKS="sendtoicon,desktopicon,quicklaunchicon"
Deselect all tasks, then select the "desktopicon", "sendtoicon" and "quicklaunchicon" (Vista & under) tasks. (Use the /MERGETASKS parameter instead if you want to keep the default set of tasks and only select/deselect some of them.)

/MERGETASKS="desktopicon"
Keep the default set of selected tasks, but additionally select the "desktopicon" tasks. (If a task name is prefixed with a "!" character, the task will be deselected.)

The reason you need this new version is because neither the old version nor universal extractor can extract the files from the data1.cab archives created with newer versions of InstallShield
