[SOLVED] How can I deploy an upgrade of my product which contains a file with version lower than the already deployed file?

How can I deploy an upgrade of my product which contains a file with version lower than the already deployed file?

I have a msi component which deploys a file MyFile.dll. I have a test machine in which my product already deployed MyFile.dll, which has version 09.99.99.99.

Now I'm writing a major upgrade which will deploy a new version of MyFile.dll with version 05.23.76.123. After execution on the test machine, MyFilee.dll is removed... I need to change or repair to correctly deploy it.

How can I force the deployment of MyFile.dll regardless of its injected version number?

PS: This is happening on our test machines only. The product we delivered to our users has files with version numbers consistent with release history.

Solution

There are several ways in Windows Installer to do this but they all have their complications. IMO I would just rebuild the same source code as the old DLL but with a newer higher version and keep it simple.
