When you have an old sof-file, there must be an older successfull Quartus run. Is the run also done with a Web edition ?  Kind regards  GPK

I am using VIP cores, the device I qould like to configure is a cyclone2. 

Yes, there are old sof-file, on the first compilation I get correct results. The previous run is also done with a quartus2 web edition.

Someone (sys admin) just set up and configured a Sophos Antivirus. 

I'tried to uninstall and reinstall the quartus, but still the same problem. Maybe I didin't search the registry.

Well, It was like the pogram hadn't write permissions, or any sectors oh the hard drive where damaged. 

I formatted my hard drive and reinstalled quartus and windows, it seems to work all properly now.
