Error during SQL Server installation: "The architecture is not supported"
The setup compares the processor architecture. Microsoft SQL Server Express only supports 64-bit operating systems. If you are using a 32-bit operating system, you can install SQL Server Express 2014 manually. This is no longer supported by Microsoft. For security reasons, however, it should not be used.
It can happen that the setup does not display this error, but it is a processor with ARM architecture. It is not possible to install SQL Server Express for these processors.
