Peter, You need to make sure you have permission in Windows to write to the IFEFFIT folder. If I remember correctly all you have to do is right click on the IFEFFIT folder, select Properties. Go to the Security Tab and then select the Edit button. Make sure that under Users all of the "allow" boxes are checked then click OK. IFEFFIT should install the updates the next time it checks for updates.

When the runner informs that updates are available, I select to download and install them. Then, the first package is downloaded, but during expanding and installation of this package the update basically stops and the runner gives an error associated with access to bin/athena.exe. Windows 7 (like Vista pretty easily stressed when you try to change software) does not inform me that a program is trying to change the system or whatever, so I don't know what to do. Is there anybody out there with similar problems and maybe, even better, a solution? Regards and many thanks, Peter Kraal. _______________________________________________ Ifeffit mailing list Ifeffit@millenia.cars.aps.anl.gov http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit
