Searching for cabarc.exe finds this:

c:\BC5\BIN\cabarc.exe
c:\cabsdk\BIN\CABARC.EXE
c:\Dokumente und Einstellungen\thomas\Desktop\downloads\Cabsdk\BIN\CABARC.EXE
c:\Programme\MicrosoftSDK\Bin\CabArc.Exe
c:\WINDOWS\Prefetch\CABARC.EXE-04C2A86A.pf

The first one in c:\bc5\bin is an old version, included in an old
borland compiler I have installed.

The one in c:\cabskd is from MS' cabinet sdk, also the one in downloads.

c:\Programme\MicrosoftSDK is the Feb 2003 Platform SDK, which I had
installed before installing VS 7.1.

So, it seems there is no cabsdk.exe in my VS 7.1 installation tree.

Ah, now I see.  Changing the code to this:

        for k, v in [(r"Software\Microsoft\VisualStudio\7.1\Setup\VS", "VS7CommonBinDir"),
                     (r"Software\Microsoft\Win32SDK\Directories", "Install Dir")]:
            try:
                key = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, k)
            except WindowsError:
                continue
            cabarc = os.path.join(_winreg.QueryValueEx(key, v)[0], r"Bin", "cabarc.exe")
            _winreg.CloseKey(key)
            if not os.path.exists(cabarc):
                continue
            break
        else:
            print "WARNING: cabarc.exe not found in registry"
            cabarc = "cabarc.exe"

makes it work, since it now finds the cabarc.exe in
c:\Programme\MicrosoftSDK.

Where is cabarc.exe on *your* system?
