Bug ID: 48242
           Summary: IXMLDOMDocument_load() paths aren't URL-unescaped
                    (Microsoft Document Explorer 2008 startup error)
           Product: Wine
           Version: 4.21
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: msxml3
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

After patching ieframe as per bug 12406, and installing and starting Microsoft
Document Explorer 2008 as per instructions there, it quickly gives a messagebox
and exits. The messagebox text is the following:

"Microsoft Document Explorer cannot be shown because the specified help
collection 'ms-help:ms.WDK.v10.6001.080214' is invalid."

The problem is that msxml3's IXMLDOMDocument_load() is called with paths of the
form "C:\Program%20Files..." and Wine doesn't URL-unescape them before trying
to open them.
