On Windows Vista, I created a custom directory C:\MikTex\tex\latex\myheader for all my header files (mostly just .tex). Now I've installed Windows 7 and I can't seem to work out how I did it the last time. I'm using TexNicCenter for compiling and it always says that it can't find the files at all.
I think I had to do texhash whenever I changed something in the directory back then, but now doing texhash does nothing. Any help?
