ISPreventDowngrade not functioning, thinks newer version found?
No matter what options we choose we get 2 outcomes:
1. It doesn't remove the old version and just installs the new version along side it 2. It complains that a newer version is found and exits out.
Old Version: 220.127.116.1193 (I know 4th digit is meaningless) New Version: 6.0.0.xxx
We have tried pretty much every option under the Advanced/Common tab. We have recreated it. Still nothing. The product has a DIFFERENT Product Code and the SAME Upgrade Code. This works fine in our InstallScript MSI packages, but the Basic MSI packages fail with this.
