Thanks Dan for your reply :) Consider that before the actual installation of Wine, I did few actions to try to solve the problem with the previous installation and one of them was the use of winetricks to load the mfc42 library, of course without any result. Consider also that before writing this post, I copied file mfc42.dll (taken from my windows system) into my /home/claudio directory where I found it is located the file bdays.ini with data used by Birthday Reminder, hoping that the application would work. Than I gave the command: wine "c:\\Programmi\\Birthday Reminder\\bday.exe" and I get the same result as reported in msg #1 [Crying or Very sad] The file mfc42.dll is copied actually into following Ubuntu directories: /home/claudio /home/claudio/.wine/drive_c/Programmi /home/claudio/.wine/drive_c/Programmi/Birthday Reminder Any idea to help? Claudio :)
