So after finding the Windows binaries compiled (and maintained) by
Max Martin Payne, I look at the contents of the zip file. I was running a 64-bit Windows installation. I had two freeglut.dll’s to copy to a suitable system folder, one for 32-bit, one for 64-bit.
Logically, I thought I’d place the 32-bit dll under C:\Windows\System32, and the 64-bit dll under C:\Windows\SysWOW64, right? Think again – it’s exactly the other way around.
Reason behind this is that SysWOW64 stands for: System Windows (32) On Windows 64. That folder contains 32-bit libraries for several 32-bit programs that have to be run on the 64-bit system. This means that the System32 folder contains all the 64-bit libraries. The reason Microsoft didn’t change the (now utterly confusing) folder name is because a lot of (badly written) software depends on having a System32 folder where it can look for dll’s, and nowhere else.
I thought someone should write this down. On the internet. Because it could have saved me a fair slice of time.
