Find out what Windows error codes mean with a free, portable program
ErrMsg is a free, portable utility which makes decoding those messages about as simple as it can get. Launch the program, type in your code, and a window appears with a straightforward version of what the error means.
You can find the ErrMsg download on FavesSoft's website -- but save yourself some scrolling and use your browser's find function and input errmsg to jump to the right spot on the page.
