Problem: You have added the Asymptote tool to TeXnicCenter, but when you hit your hotkey, you get an 'Cannot execute the command' error.
What might be going on: TeXnicCenter doesn't see the Asymptote executable.
Possible Solution: Go back to the Tools -> Customize window (click Tools, then Customize in TeXnicCenter). Then, click the Tools tab, then select Asymptote. Instead of cutting and pasting the text for the Command line, click the ... button after the Command entry box. Then, navigate to the asy.exe executable. You'll probably have to go up several levels to C:, then click Program Files, then Asymptote, then the file asy with the stylized red A next to it.
Problem: I have everything installed and the hotkey doesn't give me an error in TeXnicCenter, but when I hit the hotkey to compile my code, all that happens is that a window flashes briefly then disappears. Nothing else seems to happen.
What might be going on: Your file is saved as a .tex file, not a .asy file. (TeXnicCenter will even make it look like it's an .asy file, but it's really saved as an .asy.tex file.)
Solution: Click file, then Save As, then type your filename with the .asy extension (such as test.asy), the set the 'Save as type' field to 'All files'. This should make it a .asy file.
Problem: You can draw images with Asymptote, but it doesn't compile your file whenever you have a label containing LaTeX code (for example, the line label("",(50,50),S); as in test.asy.)
What might be going on: Either Asymptote is not finding your LaTeX compiler, or you have installed your TeX distribution (such as MikTeX) in a folder that Asymptote cannot find.
Solution: Let's say you installed miktex in the folder C:\Program Files (the default). Then there should be a subfolder texmf, containing the folder miktex, containing the folder bin, which contains your latex compiler. In your config.asy file, add the following two lines to the bottom:
texpath="C:\Program Files\texmf\miktex\bin"; dvips="C:\Program Files\texmf\miktex\bin\dvips";
