Before running the installer, ensure that:

* No previous version of MangoApps for Windows desktop is already installed.
* If a previous version exists, uninstall it and restart the machine to complete the cleanup process.
* Use the 32-bit MSI installer for machines with a 32-bit operating system and the 64-bit MSI installer for those with a 64-bit operating system.

Additionally, the installer **must be run** in administrator mode as it installs the application to the Program Files directory.
