Creating an Upgrade
Windows Installer Editor Reference
What you need to create an upgrade
The previous version or versions, which you are upgrading, must have been
installed using Windows Installer.
You need access to the .MSI of each version you are upgrading.
If you do not have access to the .MSI files, you must have the upgrade code and
version information from the .MSI files. The upgrade code is stored in the
UpgradeCode property, which is in the Properties icon in Setup Editor > Product tab.
The version is located on the Product Details page.
The product code of this installation should be different from the product codes of
the installations you will upgrade.
What is the upgrade code?
The upgrade code is a property that is set when you create a new installation. It should
be the same for a related set of applications. When the end user runs an installation on
the destination computer, Windows Installer searches for applications with the same
upgrade code.
The upgrade code is the only information required for creating an upgrade. If no other
upgrade specifications are entered, it is used as the sole factor for determining whether
the upgrade takes place. You can see the upgrade code under the Properties icon in
Setup Editor > Product tab. It is in GUID format.
To create an upgrade
1.
Select Installation Expert > Upgrades page.
2.
Click Add at the right of the page and specify the .MSI or .WSI for the previous
version of the application.
If you see a warning to update the current installation's product code, click Yes.
The Upgrade Details dialog box appears.
3.
Complete the dialog box:
Upgrade Code
If you specified an .MSI or .WSI to upgrade, this is filled in with that .MSI's
upgrade code. If you did not specify an .MSI, you must enter the upgrade code
of the installation you want to upgrade.
