Given the initial mistake, there isn't a good solution. Anything you do will be a very large undocumented hack.

I would recommend blocking and asking users to manually remove the old product.

The cure could easily end up being worse than the disease.

Subject: Re: [wix-users] Replacing old cached bundle.exe

Hi Farrukh and Jacob,

I need to do this because I want to upgrade computers with my software that has the old installer cached (that doesn't support upgrade/silent uninstall) and I don't want them to uninstall the old version first.

I didn't write a custom action that prevents uninstalling, uninstalling is possible (in a non silent way), I just don't want to ask them to do that.

My new installer does support upgrading and silent installation, I just don't know how to "upgrade" the old cached installer.

Why is swapping the bundle not possible?
How can I create a patch bundle that upgrades the existing bundle? What's the way to do that?

Thanks in advance!!
