NO Dear.....

I dont want to upgrade the client....

This is a fresh installation.....

Follow the above document
insted of VPremote path you need to give the .exe path ( package you have created)

You can put Setup.exe file on www server.
Consumer will be able to download installation package thanks link to the server provided by You.
After that he will need to execute it manually.

Thanks for ur reply Rafeeq.

But I need when the user clicked on setup.exe it directly execute and install on my fresh system.

But Now as per the above KB, when I click on setup.exe then first it is asking me to save exe file then after saving file we have to manually run the executable file to start installation.

Any suggestion.
