Problem/Fix for ATENA v3.3.0 installation
Symptoms: after ATENA 3.3.0 is installed, ATENA 2D crashes at startup with an initialisation error in FAVystup.dll or "catasrophic failure".
Reason: some DLLs were not properly registered
Solution: make sure you have administrator rights. Unpack rega2d.zip
(e.g. into c:\temp) and run rega2d.bat. Try to run ATENA 2D, it should start normally now.
