Not acceptable? English is the lingua de franca of technology.
I rather have a detailed error report in one language and then have to find someone who speaks it to translate it (if Google doesn't do a good enough job), than fifteen poorly written versions. Not to mention, those error screens should be as minimal as possible in terms of features so less goes wrong.
I don't want animations, fancy colors, dealing with the horror show that is localization, or anything of the sort. Because the system when it hits a bsod is in an undefined state, so it's best to exercise as little as possible of the system, just enough to get the error message out.
