SQL Server 2014 Express

Is that the function Registry.DoesKeyExist, check in different registry depending on whether the operating system is 32 bits or 64 bits?

Yes. If you build a native 64-bit setup, this action will read the 64-bit registry. If you build a 32-bit setup, Registry.DoesKeyExist() will read in the 32-bit registry. If you use a 32-bit setup to install a 64-bit application, the registry keys of that application cannot be found without help using the 32-bit function.

I'm trying to install 32-bit SQL on a 64-bit Windows Server 2016.
The first time it installs well, but then it does not detect that it is already installed.

In this case, the registry keys read by will be found at HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\ Microsoft SQL Server.

Forgive my English, and I hope you understand my query

Not a native speaker myself, so no worries at all.
