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:
- 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
- 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.
(Note: Upon completing the software installation, the World Wide Web Publishing Service restart is required)
