How to uninstall MinGW-w64 C/C++ Compiler and start over?

I accidentally installed the latest version of MinGW-w64 C/C++ Compiler instead of the recommended. Now when I uninstall it and try to install it again, I don't seem to get the option of choosing anymore?

How can I re-install the GCC version 4.9.2?
