wierd problem... VISTA - virtualization problem...

[Vedam Shashank]

I am totally perplexed with this....

I am tryin to save a file (XML), using a certain save method from MSXML2::IXMLDOMDocument2.

It has worked well so far.(XP, Win2000, server,.....Vista too with Virtualization on)
Now in vista, with virtualization disabled, I am unable to save the same absolutely anywhere... except C:\Users\<User_Name>. This is the only location I am able to save the file.
I can't save the same under C drive... nor in another partion - D drive.... WOW....

I need to save the same under <%ALLUSERSPROFILE%> (Program Data in case of Vista).
(The version of msxml I am using is msxml2.dll)

any help would be great


EDIT:
Forgot to mention earlier.... the error code returned is... E_ACCESSDENIED (even while trying to create a new file).
Just a thought... Do I need to use a different version of msxml for vista??
