Running EndNote X3 under WinXP I can no longer do direct exporting from any sites. (It used to work fine with X1). An error message of the type “*.enw is not a valid Win32 application” is generated. (For those sites that allow saving the *.enw file to a file, that option still works.) have tried uninstalling and reinstalling the program, and I have all the latest XP updates installed. I wrote to EndNote tech support two weeks ago but have not received a reply. User community help would be most welcome.
