The error is that MSCOMCTL.OCX which should be on your
system, isn't.
The installer program (and many many others) use this DLL to provide widgets like progress bars.

It may be that the file exists on your system but is just not correctly registered.

There should be a file called REGSVR32.EXE on your WinNT\System32 directory and also a file called MSCOMCTL.OCX in the same directory.

If not, you will have to get them, maybe from your NT CD or perhaps by downloading them from somewhere on the Microsoft site.
Once the files are there, from the command line type:
  REGSVR32 MSCOMCTL.OCX

The installer should then work.

Alternatively, you can load the installer.exe into winzip and manually install the components.
