ldodd1.5524942620953406E12 asked a question.

Previous Install in Visual Studio
We have a VB.NET project that a Setup and Deployment package was created in Visual Studio. This installation works just fine but we wanted more and have now written a new installation using InstallShield Premier 2008. The question I have is how do I install the product to a machine that already has a previous version of the installation using Visual Studio? The best case would be for this new InstallShield install to be able to replace the files in the previous install and then install the files in its package. Please advise the best way to accomplish this. Any help would be appreciated.

    The simplest, most flexible, and safest approach would be to get the UpgradeCode from your previous installer, and author a major upgrade item in your InstallShield project. Properly authored, this will transparently remove the old package when the new one is installed.

    Thank you for your help. I have already created a Basic MSI package for the new install. What will be involved in making this a Major Upgrade Package for this install. Any direction that you can give me on this one would be really appreciated.

    I see the Add Major upgrade item and I do have the Upgrade Code for the latest installation. The problem that I may have is that there are several people who do not have the latest installation installed. They may have an older version number and I do not hav the Upgrade Codes from those installation. Will I have to make sure that everyone is on the latest version before they can use my new Installshield install or will this installation uninstall any version of the old program? It mentions that the upgrade may remove data that the user has created and I may need to create a custom action to do a backup of this data first. has this been anyone's experience? Any help wth this would be apprecaited.
