SYMPTOMS
When you attempt to start a program from the desktop, the Start menu, a shortcut, or from a file association, you may receive one of the following error messages:

Access to the specified device, path or file is denied.

-or-

Access to the driver, specified path, or file is denied.

NOTE: This problem only affects programs whose executable files are located in folders within the Program Files folder.



CAUSE
These error messages can occur if any of the following conditions exists:
 * You have a Program folder on the same drive as the Program Files folder.
 * You are trying to run a program that does not write quoted path strings containing long file names into the registry. The execution of a process is handled by the Win32 CreateProcess API. CreateProcess is unable to distinguish between spaces in long file names, and spaces delimiting arguments to the function. If a quoted string is passed to the API, CreateProcess is able to make this distinction and starts the program as expected.
 * In Windows Explorer, the view option is set to hide DLLs. This is the default setting and should be changed to "Show all Files" if you receive this error message when running a 16-bit program.
