Be very careful when editing the Registry!
You need to navigate to the "bottom" of the tree path shown below (watch for
line-wrapping -- it's all one line):
HKEY_CLASSES_ROOT\TypeLib\{5B87B6F0-17C8-11D0-AD41-00A0C90DC8D9}\8.0\0\win32
Expand HKEY_CLASSES_ROOT tree.
Navigate to TypeLib and expand it.
Navigate to {5B87B6F0-17C8-11D0-AD41-00A0C90DC8D9} and expand it.
Navigate to 8.0 and expand it.
Navigate to 0 and expand it.
Navigate to win32 and expand it.
At this key, you'll see (Default) on the right side of the RegEdit window.
The Data string needs to be the path to the accwiz.dll file. If it's not,
edit the Data to change the string to be the correct path.
