I thought I'd copy these tips for getting Milkdrop2 working on Windows 8.1, in case it helps someone out
I had to do all the steps to get it working on the new system (8.1 arggghhhh)...
1). Install
2). Import .reg file
3). Manually edit registry
as mentioned in the thread, PLUS one additional step;
4). Install the DirectX legacy pack from Microsoft to get it working.
NOTE: I had to close some Chrome processes manually and clean out the temp install directory (i.e. c:/users/your_name/AppData/Local/Temp/) in order to successfully complete the DX installation. It was throwing an error and failing.
Here's the link for the DirectX legacy support installer (it won't affect your DirectX 11 or 12 setup):
