Is this a web project or a pc/windows app project?

Hi,

Just compile your project again with plateform option x86.
If you use "Any CPU" then it will detect the plateform and try to run the application accordingly.
In 64 Bit, this provider is not available or not registered.

So, You need to compile your project for specific plateform x86.
Because, x64 OS comes with backward compatibality.
Now if you compile with x86 option then OS will provide all the services as 32 bit.

For more clarification You can go through with this thread

What do you mean?
Do you want a competition here?

Not really... Didn't saw your post until I posted mine - and both answers are saying basically the same thing. Thought the smiley will be enough to avoid possible confusion.
No hard feelings I hope. Take care :)

Actually, I will say you the same thing if you ask for competition.
Take Care:)

Hi,

Apparently there is no x64 version for it. Try compiling the app against the x86 option (set in the project configuration settings). Take a look at this thread @ msdn forums for more information.
