Issue: When upgrading qemu-ga using the msi from an old version to a newer one, the upgrade is not allowed by the msi showing this error message "Another version of this product is already installed." BZ# 1536331: https://bugzilla.redhat.com/show_bug.cgi?id=1536331 Fix: For the upgrade to be allowed by the msi the WiX file must provide three things: 1. Changing product's Id. (assigning it to "*") 2. Constant product's UpgradeId. (exists) 3. Changing version.
