SYMPTOM
When performing an upgrade of a program from the Messageware OWA Server Suite family using the MasterInstaller.exe, an unexpected error may occur during the uninstall and/or install phase that can leave the software in an unsuitable state.
SOLUTION
There are two solutions available:
1. A server reboot can release a hung process and may place the server in a clean state where the Master Installer may continue with the installation task
2. A manual removal of the software will need to be performed. The software dependencies and registry entries will need to be removed/renamed on the affected Exchange server. This will allow the Master Installer program to re-install the affected software.
The Messageware AttachView will be covered throughout but this solution can be applied to any of the other Messageware OWA Server Suite software.
Note: Upon completing the software installation, the World Wide Web Publishing Service restart is required.
