Either install Apache etc. from different distributors, or switch over to Linux (Xampp runs in 64bit on Linux). Many solutions, all better than waiting, waiting, waiting.... Nobody can give you a guarantee, that there ever will be a 64bit Xampp Windows version.
I am trying to install xamp onto win server 2016 64bit and I am just getting installation failed. Before I spend time looking for other reasons as to why, Can anyone confirm that xamp 32bit will or will not install on this setup.
