Final answer:
The original file name of an MSI must remain unchanged for the software to install properly, as it often contains identifiers required by the Windows Installer.
Step-by-step explanation:
The question you've asked pertains to the installation of software on a computer using an MSI file, which is a package format used by Windows Installer. The file name of an MSI is important because it often contains a product code, version number or other identifiers that the Windows Installer requires to manage the installation, upgrade, or removal of the software properly. If these identifiers are altered, it may prevent the MSI from installing correctly. Therefore, when you are installing software from an MSI file, it is crucial to ensure the original file name remains the same.
