During the installation of Sophos products, you may get errors that provide insufficient information about what has occurred. As all Sophos products for Windows use MSIs (Microsoft Installers) to perform the installation, it is very useful to check the MSI installer logs to gather more information about the error. This may allow you to resolve the problem yourself or provide vital information that you can give to Sophos Technical Support.
During installation, Sophos products create msi logs, which by default are created in the Temp directory. This can be located by typing %temp% into the address bar in Windows Explorer.
