Supporting Side By Side Installation

Recently we came across an issue to support side by side installation.

We have a customer that installed version 1.0.0.0
Now we started publishing version 2.0.0.0.

This customer wants to install version 2.0.0.0 next to version 1.0.0.0 on the same server(side by side) like microsoft and other companies do it with thier products.

However our installation is not simple. it includes Services, dll/COM Registration, writing to the registry, creating virtual directories and application pool, GUIDs etc.

The problem is I dont even know where to begin and how to do it most efficiently.

Any help will be appreciated Thanks

You might have to change the GUID for every component which gets registered during installation. Here's the bare minimum that needs to be done:
