upgrade without key file

[azc168]

Hello,

I have an application that was installed without setting component key files. Now I install a newer version of the application that has component key files set on top of the old version. Application works fine at this point.
Then I uninstall the old version, all the files are gone since component key files were not set in the old version.

Is there anything I can do in the new version msm/msi to work around the problem? The old version is already released and can not be changed so I can not set component key there. But the new version is still being developed and I can do whatever to make the upgrade feature work. The support of upgrade is a requirment.

I'm running out of ideas and your help is highly appreciated.

Thanks,

Tianli

The best option is a Major Upgrade.

Minor Upgrades and Patches rely on component keys to properly deliver updates. However, the component keys could not be fixed or otherwise worked-around without much hacking.
