This is Satyadeep.
1. Although I could install in about 5-6 laptops, the process did not work
for 3 laptops.
2. During uninstall, Firefox is not visible in control panel programs and features.
3. Also, if the installation is repeated a second time on a laptop with firefox
installed earlier through software deployment, installation is not working.
To do this, I have removed laptop from domain and added again a second
time for installation.
