Windows 7 x64 SP1, Calibre 0.9.8 x86 and x64

If I export any book in any format from Calibre to any folder on the hard drive, the export takes place correctly and I can subsequently access and read the file.
But, just before the process completes I get this error:

calibre, version 0.9.8
ERROR: Unhandled exception: <b>WindowsError</b>:[Error 1155] No application is associated with

the specified file for this operation: u'C:\\Users\\SysAdmin\\Desktop'

Traceback (most recent call last):

WindowsError: [Error 1155] No application is associated with the specified file for this

I'm not sure what Calibre is attempting to do at this time (open the target folder?), but it isn't working.
All exported formats are flagged in Preferences for internal viewing by Calibre

Has anyone else come across this and in particular have a fix?

Thanks
