NEEDSUPGRADE always set to false

[cybermantec]

Hi,

i am using IA 2010 in the following situation

created a project called Setup A 5.0, product code of AAA and the revision code of 123

created a project called Setup A 6.0, product code of AAA and the revision code of 456

The use case is, my customer installs the software with Setup A 5.0 a few month ago. Now i want to upgrade this version to 6.0, uninstalling the version 5.0 and installing the version 6.0 into a different target folder.

I have no success. I have put a messagebox in the first line of my script to display the value of NEEDSUGPRADE. And this variable is always FALSE.

How can i replace a old version with my new version ?

Thanks

Ulrich

Dear Ulrich,

I really suppose that exist something wrong somewhere with your project settings.

By default InstallAware handles the update process automatically.

Just having a new revision code with a project build ( ... which it is by default) causes the upgrade process to be triggered ( ... with same PRODUCTCODE and UPGRADECODE) .

For example try the following;
- Create a new project from scratch, leave all project settings as these are by default.
- Build the project and install the package over a target machine.
- Rebuild the project ( ... by default the revision code will be regenerated with ne new build).
- Run the new package build over the same target machine.
I'm sure the previous version will be uninstalled first.

Let me know.

Hi Francesco,

i did a new project and it works as expected.

But what could be wrong with my former created project ? We are using IA since about 2 years. We want to roll out a new version of our software and therefor we need first to uninstall the old version and then install the new version.

Thanks

Dear Ulrich,

Verify that both your projects shares the same PRODUCTCODE and UPGRADECODE, but a different REVISIONCODE.
These are the minum required settings to have upgrade functionality working.

Let me know.

Ulrich, did you ever figure out what was wrong with the old project?
