Add-In installation

S

Selgin

Hi all,

I've created a VB6 COM Add-In (self-registering DLL file) for Outlook 2000 and have used Windows Installer 1.1 to create a setup .msi file to deploy it. It all works fine, but for one issue.

If I update the DLL (and increase the version number) and build a new .msi with the updated DLL, when I run the setup it doesn't overwrite the existing DLL, thus not reflecting the updated DLL. The setup asks me if I want to repair or remove the add-in, and if I choose repair it doesn't update the DLL, just leaves the current existing one.

I would like it to overwrite the installed DLL without having to uninstall and then install the updated add-in. Can anyone please help?

Thanks in advance,
Selgin
