Opening Windows Vista Files with Online Help
Sometimes Windows Vista cannot open a file because the needed software is not on your PC. Microsoft offers a Web service to help you out when Vista cannot open a file.
It’s frustrating when several programs fight to open your file. But it’s even worse when no program ponies up to the task. Double-clicking your file merely summons the cryptic error message shown in the following figure.
