Hi All,

I'm using IS 11 Pro and I want to perform a major upgrade of the old setup.
But in previous version I have a remove warning message box, which is shown during uninstallation.
So this message box also appears during major upgrade, but I don't want it to appear.
I tried to change the major upgrade settings "Completely uninstall then install" to "Install then remove unneeded files", but the result is the same.
Maybe it is possible to disallow message boxes at all??
Can anyone help me with this problem?

Thanks,
Hovik

You probably should put a condition on the message box in the old version.
In which sequence did you insert the MessageBox, and how do you display it (a Windows Installer dialog, or a custom action?)

Thanks Stefan,
I am using custom action for displaying the message box, but the problem is that I can't do any changes in previous version. But I am very interested what condition can I put, that installer will recognize if it is uninstallion or major upgrade?
Now I am trying in other way. If I can to call the uninstallation silently the problem will be solved. But is it possible to change the uninstall mode during major upgrade?
Or maybe you know from where the installer takes the command-line string for uninstalling previous setup. Because if it takes from registry I can change the string adding /qn at the end.
Any ideas?

Thanks,
Hovik

The UPGRADINGPRODUCTCODE property will be set if the old version is being removed by a major upgrade.

A major upgrade should also uninstall the previous version in silent mode. If you have a setup that you cannot uninstall like this, one way to fix it is to patch the existing install using a minor upgrade and then have the patch remove or condition the custom action in question.
