d3d11.dll problem

[LunaMoo]

I guess Henrik does work on adding d3d11 backend and there's a potential he messed something up or intentionally plans to remove support for older windows platforms(dx10+ does come as part of ms OS, not as separate download) as they're not maintained and potentially buggy anyway, but I don't really know anything about such plans, also last release 1.3 would probably still work even if that would be the case(if not, try even older;p).

Dll problems like that are easier explained by external injectors through. For example external third party software like all those shader or gamepad injectors requiring and if you used any of such it just means that software was not ment to run on your OS and you should remove it. Also similar injectors can contain malicious code ie. very popular to place bitcoin miners in emulators, if you downloaded ppsspp from any shady site, it quite likely came with an unwanted bonus;p.

So either way I would recommend removing whatever you got and usling clean ppsspp from official download site.
