How to overwrite the previous version?

[John78]

Hi,

I am using "InstallShield 2013 Limited Edition for Visual Studio".

When I try to install the package multiple times I am getting the below mentioned 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.

Also, if I change the product code it creates multiple entries under Add/Remove Programs.

Kindly let me know how to avoid these issues.

Thanks

A "major upgrade" will uninstall the currently installed version and install the version from your installer.

You would need to change
*Package code
*Product version
*Product code

You will also want to create an upgrade entry in the Upgrade Paths view

Thanks for your reply. I am not sure where I can find Package code.

I have changed Product version and Product code and it is not prompting me saying "Another version of this product is already installed ...". However, it is not uninstalling the existing version. In Add/Remove Programs I am seeing both versions of my product.

Thanks

The package code changes each time you build, so there is no option in the LE edition to change it. As long as the other options mentioned have been changed, you should be all set.

Do the Upgrade Codes match between the two projects ?

You can find the Upgrade Code option under the "Upgrades Paths" view after you have created a new upgrade path.
