How To Install Two Versions Of Same Software
I have two versions of the same application. I desire to install them to the aforementioned PC. When I install I get the error :
Another version of this product is already installed. Installation of this version cannot go on. To configure or remove the existing version of this production, use Add/Remove Programs on the Control Console.
Is there something I tin can practice in the version settings?

I am non sure why you need two version are installed in the aforementioned PC.
If yous want, you lot can change the version(please find screenshot below e.grand ii.seven => 2.8). There volition exist a popup windows that ask you lot to change ProductCode. If you say yep to the dialog. VS volition change your production 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 y'all will demand to change the UpgradeCode.
From higher up Link
the windows installer will use the UpgradeCode to make up one's mind if previous versions of this product are already present on the system.

Put them in dissimilar directories (like Microsoft Role does, for example). c:\Program Files\Visitor\Production\Version

But software version is stored in registry. Even if you practice equally Adriano said, still information technology will give this fault.

@NikhilAgrawal yep and no. I suppose he is using Windows Installer. Its behavior is defined in the installation project backdrop, how it works can be customized (if he wants to keep side-past-side installations) using ProductCode, Version and UpgradeCode properties.
