How to have two versions of the same application installed on the same PC?

I have two versions of the same application. I want to install them to the same PC. When I install I get the error :

Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel.

Is there something I can do in the version settings?

I am not sure why you need two version are installed in the same PC.

If you want, you can change the version(please find screenshot below e.g 2.7 => 2.8). There will be a popup windows that ask you to change ProductCode. If you say yes to the dialog. VS will change your product code for you. You can install newer version.

This MSDN Blog gives a good explaination of what the UpgradeCode, ProductCode and PackageCodes are used for. It looks like you will need to change the UpgradeCode.

From above Link

the windows installer will use the UpgradeCode to decide if previous versions of this product are already present on the system.
