I do install it on 2012 R2, I think maybe it’s your system environment.
When i installed ,it;s can’t auto install mysql ,so i installed Microsoft Visual C++ 2015-2022 x86/x64 manually , and mysql-connector-odbc-8.0.21 maybe need Visual Studio 2019 x64(I installed it manually )
and you must install Rewrite module for IIS as Carl told me, it’s can’t auto config.
When you setup to the prerequisites window , you can check what it requirement and check your control panel to find if all installed, If not you can install the requirement manually .
Before the install finished, you can find the requirement soft in the temp folder.
