Deployment Issue

Question

Hello,

I've built a software and that is being used by our company's users. I've created a installer (setup.exe) of this software. Problem is that every time I update this software, I need to rebuild the installer and each time users need to take this update by uninstalling the previous one & installing the new one. Now, this is something cumbersome for me & user. I want to do in such a way like I will be installing the software into a server and give the shortcut of this software to each user. I think you get my point whatever I want or Is there any other way to do this?

If you could help me, it will be very helpful for me.

Regards,
Shomen
