If there's a command window, you may have run into the WSH stdout-buffer
bug. Does your installer output something into the command windows? If
it's too much, you'll need to redirect it to >NUL.

Are there any children hanging under the cscript.exe running wpkg? This
may give you a clue what process is hanging. If it's a cmd.exe directly
under cscript, it certainly may be the stdout-bug. That points to
redirecting the output of the script to >NUL
If I just open a command prompt window and run the installer from there (not invoking
wpkg), it does not output any text on the command line. It does pop up some windows
progress boxes during the install, but nothing on the command line.
Another possible hint is that the installer proceeds far enough to create the
uninstall entry in "Programs and Features" or whatever "Add/Remove Programs" is
called in Windows 7. But it hangs before it finishes the full install. This means
that the installer actually tries to run, it doesn't wait at the beginning for some
sort of user confirmation.
