Installer Class Not Calling Overridden Uninstall Method when Multi Instance enabled

[sysadmin-blr]

Hi Team,

I am installing  my product with multiple instances enabled.  Lets consider the below installation sequence.

1. Install base Instance ( Run the setup very first time)

2. Install First Instance

3. Install Second Instance

When I try to uninstall  the Second Instance, Overridden Uninstall Method is not firing.  Same problem for uninstall  the first Instance also.

But when I try to uninstall the base Instance , Overridden Uninstall Method is firing as expected.

Is there any setting i need to update to fix this issue?

Thanks,

Ramesh P.

Instances are equivalent, 1-n. What do you mean "Base Instance"? How does that differ from Instance 1 or 2?

Hi Team,
What I mean for "Base Instance" is, Run and install the setup first time. When we run the same setup next time , i refers it as first instance. If we run the same setup next time , i refers it as second instance. Please let us know if you need further information.
Thanks, Ramesh.P

Do you have separate 'ProductCode'  Values for each instance?

Please describe the " Overridden Uninstall Method" that you speak of. Is this a custom action? Properly done, there should not be no need for separate uninstall behavior.

Hi Team,

Yes. We have defined separate Product code for each instance.

Please refer the attachment for " Overridden Uninstall method" details.

Thanks,
