For several years we have used IS 12 to create the installers for our product, and I am in the process of rewriting our installer with IS 2010. This is an installscript project.
With our old installer, the upgrade procedure was to uninstall the old version (leaving some files behind) and then install the newer version on top of it. One of the main things we're trying to do with this rewrite is to start using the built-in upgrade features of InstallShield.
Here is my current setup: - Our builds are created by an Ant script. The Ant script builds all the files for our product, then executes IsCmdBld.exe to create the installation with those files. - The Ant script creates an environment variable containing the product version for this particular build in the form "1.2.3". - The InstallShield project has General Info > Product Version set to an environment path variable that grabs this value.
This seems to work for upgrading...mostly. I manually changed the version in the IS project to get two installers, each with identical files, but different version numbers. Call them v1 and v2.
I install v1, then run the v2 installer and it performs an upgrade, as expected. But then when I go into Add/Remove Programs, the version number listed is still v1. If I try running the v2 installer again, it still offers to upgrade, even though it should already be installed. I would expect to get the maintenance options.
The IS documentation hasn't been very helpful. Can anyone tell me where I'm going wrong here?
Thank you for the reply, but it doesn't look like the information in that thread applies to our project. We are using pure installscript, not installscript msi. Also, we do not end up with 2 entries in Add/Remove programs. There is only one entry, but it displays the v1 information even after an upgrade to v2.
script will run OnupdateUIBefore(), instead of MaintUI() if its upgrade. Checks for version for doing this. For upgrade u need version change in any x, in x.x.x.y version
OnUpdateUIBefore is run when trying to upgrade, so that makes it seem like it's picking up the correct version number and doing what it's supposed to. It's only the version # in add/remove programs that doesn't get updated. I have customized OnUpdateUIBefore and OnUpdateUIAfter. Do I have to manually change the add/remove programs entry in one of these functions?
