In case you mean that your system freezes during installing wine using the ubuntu software manager (you weren't too precise with your question): You could try doing it per command line and redirecting the output to a file so you get a chance to read errors that may occur during the installation process at a later time. e.g. try this in a new terminal: Code: gksudo apt-get install wine > winelog.txt By the way - does your system really freeze or just the screen? e.g. is the hdd led still blinking after freeze etc.? Also it's always helpful to provide information of the hardware/software the error occurs on, in this case: - What linux distribution are you using? Ubuntu? Debian? Suse? Mandriva? etc... - Is that linux distribution 32 or 64 bit? ... I'm sorta linux noob myself though, Jay
