WebDAV for Vista x64

After downloading the update at Download details: Software Update for Web Folders (KB907306)

I was able to successfully use WebDAV on my 32 bit Vista. However, even after installing the update on my x64 Vista it still does not work when I try to use the Map Network Drive route. I need to use the WebDAV for work. I have seen many threads on this issue but they were all over 200 days old. There didnt seem to be any resolution. Is there an update or a work-around for x64 Vista that allows the use of WebDAV?

Please Help

Same problem for me. I have had several discussions with MS network tech support and get mixed answers.
"High priority to be fixed" on down to "working as designed". Something about Rosebud not compatible with 64 bit OS, either XP or Vista. I have been told that WebDAV does not work with any MS x64 OS but does work in Linux x64
