Two Installation of the same Package

Hi gurus,

i need to know, how i can install 2 versions of the same Application (but different versions) on my machine.

Background :

I have written an C#-application that works fine. It's installed on my machine by publishing it via VS 2008. It shows up in ControlPanel/Software.

Now i have modified this application and would like to install it parallel to the previous one due to testing purposes.

When installing the newer version, i receive a message, that a different version is already installed and i should use ControlPanel/Software to remove it prior to installation of Version 2.

But i need to have both versions installed.

How do i accomplish that ?

Thanks in advance!

Create a new installer with new installation paths, product names, etc so nothing conflicts on the filesystem then run the second installer. On the installer you have a "ProductCode" property that determines if the application is already installed -- and your product code is the same if you the same installer twice.

Dont just change the product code and run the installer again though because they will both try to install to the same application directory and overwrite eachother or the installer will fail if you don't replace the files.
