Incase if the above download link is not working for downloading Msizap.exe then anyone can also download it from this link. The msizap tool seems to be removed from the microsoft website that ships as part of the Windows Installer SDK. It seems to be working fine when I tried it, so if you are in need of this tool due to slow network on your computer then you can easily download this standalone file on your computer.

If anyone doesnt know how to use Msizap.exe file then I will explain it here how to use it. After downloading the file, you need to press Start and then in Run type cmd. After that navigate on the command prompt to where this file is located. I usually placed the file in \%systemroot%\msizap.exe so that it was all ready to in my path. After that when I had the location down then I just typed this "msizap.exe !G" without quotes and it worked fine.
