Why am I getting a Windows Installer package error during MetaDefender Core v5.15.0 update?
This article applies to MetaDefender Core v5.15.0 releases deployed on Windows.
Issue:
When performing an update on Windows versions of MetaDefender Core v5.15.0, the following error occurs:

"There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor."
Resolution:
The reason might be a missing latest version of Visual C++ Redistributable. You can download Visual C++ Redistributable from Latest supported Visual C++ Redistributable downloads
If the issue persists, please try running the v5.15.0 installer again with logging enabled, using a command like the following to capture a detailed installation log:
msiexec /i "C:\installer\ometascan-5.2.1-1-x64.msi" /L*V "C:\log\example.log"
Before running the command, please create a file (e.g., example.log) under your preferred path to store the installation logs.
Make sure to update the installer path and log file path to match your system. Once done, please send the generated log file to us and proceed to create a support case or chatting with our support engineer.
