On Windows 7, I'm trying to install the desktop app but get the error

"C:\Program Files\Pogoplug\dokance.dll failed to register. HRESULT-2147024703 Contact your support personnel."

I'm using the latest version of Pogo app and updated Win7.  Rebooted.  Tried all of the common tricks.

I've tried to uninstall in order to reinstall, but when trying to uninstall I get the following:

"The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. There error code is 2753."

Any help would be greatly appreciated.  Thanks.
