My Athlon-processor desktop computer uses Microsoft Windows XP Home Edition with Service Pack 3. To protect against malware, I use the Symantec Endpoint Protection program, which seems to be an institutional version of the Norton internet security products. I installed VMware Player 2.5.2 build 156735 (the most recent version). I downloaded Sage 3.4 for Windows, checked its MD5sum, and unzipped the downloaded file to directory d:\sage-vmware-3.4. When within that directory I click on sage_vmx.vmx, VMPlayer starts up and eventually shows a sage login: prompt, which prompt is immediately preceded by instructions to type one of the options (1) notebook, (2) off, (3) manage, or (4) sage. Options (1) and (4) appear to be broken: (1) When I type notebook at the prompt, a screenful of information is flashed too quick to read. Thesage login: prompt then appears again, together with the same instructions as before. Towards the end of that briefly-displayed screen of information, I see an instruction to open Firefox to some internet address; but because of the very short display time I'm not able to read that address. (2) Typing off at the prompt causes VMplayer to shut down, which is the correct behavior. (3) Typing manage at the prompt gets me to a man...@sage: prompt from which I can become the Ubuntu root user by typing sudo su. This also is correct behavior. (4) When I type sage at the prompt, I again get a briefly-displayed screenful of information followed by a return to the login prompt. I have no problem running Sage on my notebook computer, on which are installed the same versions of VMplayer and Sage. (The notebook computer runs under Microsoft Windows XP Media Edition with Service Pack 3 and has Symantec Endpoint Protection.) However I want to run Sage on my desktop computer, which has a more comfortable keyboard and much more screen real estate. Apparently the Windows version of Sage runs under an Ubuntu Linux virtual machine. Any instructions should not presume expertise with Linux, an operating system with regards to which I am a newbie. Thanks in advance for your help. type login: manage and then type sage. What does the error message say? Can you make a screenshot?

Greg Grunberg The screenshot reveals that your CPU is not advanced enough to run this binary build of Sage, i.e. it is missing SSE3 instructions. You can force it to run anyway (see the message Sage is printing), but this will result in Sage exiting during runtime due to illegal instruction error messages if you execute certain code, i.e. large linear algebra problems (where large is roughly a determinant for a 90x90 matrix over ZZ for example). Binaries for Sage 3.4.1 will be build in a mode that only requires SSE2 and those binaries should be available in about 48 hours.

Ok, I didn't look too closely and then didn't write this email immediately, so my bad. That seems like a bug, since the build machine has sse3, but probably his doesn't. Weird. pni == sse3, so no surprises here. But at least on my end there are no plans to build an SSE only, i.e. no SSE2 only binary for 32 bits since those CPUs are exceedingly rare and accomplishing this is a lot of work and other tasks I have take way higher priority. So the only real option is to build from sources inside the VMWare machine. can force it to run anyway (see the message Sage is printing), but this will result in Sage exiting during runtime due to illegal instruction error messages if you execute certain code, i.e. large linear algebra problems (where large is roughly a determinant for a 90x90 matrix over ZZ for example).
