Thread: Multiple Installations...

    Thumbs down Multiple Installations...


    I'm working with the Basic MSI Project to do installation regardless if a previous install exists or not. I bump up the version number and changed the Product Code; hoping that the install will be a fresh one, which means it should remove the existing one and then install a new one. But the result is that the Install Shield did not remove the existing one, but installed a 2nd copy of the installation.

    Anyone can think of something I might have missed?

    Thanks for your info.

    You'll want to look into major upgrades, which do what you're describing. By default, MSI uses the ProductCode value to identify a product; any two products with different product codes are considered unrelated unless you populate the Upgrade table, which is what the major upgrade process uses.

    Thanks. Works now.

    After keep the Upgrade Code the same, it works as expected. Thanks for your help.
