Windows Updates also uses the Windows Installer to deploy the updates and if your software uses the Windows Installer as well, then this could be a reason it got corrupted. The only way to fix it is to trigger the Repair feature available when you're trying to run the installer again. If that's not possible, use the official installer and complete the installation.
Most likely you will encounter issues while installing or repairing, therefore try using Revo Uninstaller. Revo will force the uninstall part and then you can install Calendar Creator 10 normally.
