The Windows agent installer did not correctly set and clear the post-install flag due to reading MSI product information from the wrong registry location. This caused the automatic update process to malfunction, and in particular could complicate updates of the Python module.
Starting with this release, the installer reads MSI information from the correct WOW6432Node registry path, ensuring the post-install flag is properly managed and the auto update process works as expected.
