Pending Windows Updates can sometimes lock files or services required by the MSI installer, causing error 1603. The workaround is to install all pending updates and then reboot your computer before running the MSI installation again. Fully updated systems are less likely to exhibit installation problems. Ensure you have a stable internet connection to facilitate the update installation.
